For a panel-mount SPD rated at 80 kA, my best overall pick is the ZDWXMGUY 140 V DC, 2-pole device because its stated voltage and pole count make it a direct fit for buyers seeking DC panel protection. The 80 kA Type 1 model with remote signaling stands out for systems that need status reporting, while the 1000 V DC, 3-pole SPD is the more relevant direction for high-voltage DC applications. The key tradeoff is that an 80 kA figure alone does not establish compatibility: voltage, AC or DC service, pole configuration, mounting, and protection type all matter. I compare those fit factors alongside the available product details, rather than treating similar ratings as interchangeable.

Key Takeaways
- Several listings share a 140 V DC, 2-pole, 80 kA specification. ZDWXMGUY, DMITIZYN, KIQPEEFK, QMOSSUSY, THPHNB, and CKIOEVZ appear to address a similar application, so confirm datasheet details and certification before choosing among them.
- The 80 kA rating does not make these devices interchangeable. The lineup spans DC and AC products, 1-pole through 3+1 configurations, and Type 1 and Type 2 devices.
- Remote signaling is a distinct advantage, not a substitute for electrical fit. The 3+1 Type 1 model adds a status-reporting feature, but its 220/380 V configuration must match the installation.
- The 1000 V DC, 3-pole model serves a different system class from the 140 V DC, 2-pole options; the higher voltage specification does not make it a general upgrade.
- Mounting and supporting specifications remain unclear from product names alone. Verify enclosure fit, DIN-rail or panel requirements, protection ratings, and manufacturer documentation before ordering.

More Details on Our Top Picks
ZDWXMGUY 140V DC 2-Pole Surge Protective Device, 80kA
The ZDWXMGUY suits buyers who need an 80kA Type 2 protector for a 140V DC system and want a clearly stated fit for solar, telecom, or industrial use. Its 40kA nominal discharge rating and ≤3.6kV protection level provide useful selection details, while two green status indicators let a panel operator check device status without opening the enclosure. Like the DMITIZYN and KIQPEEFK units, it mounts on DIN rail and shares the same 2-pole, 140V DC profile; the listed application range gives this model the clearest stated case for solar and industrial DC panels. The tradeoff is its 140V DC limit: it is not a substitute for an AC protector or a higher-voltage DC unit. Buyers should also verify coordination and system compatibility with the equipment manufacturer before installation.
Pros:- 80kA maximum surge current with a stated 40kA nominal discharge current
- Two green indicators provide a visible status check

Our verdict“Choose the ZDWXMGUY for a 140V DC solar or industrial panel when its clearly stated applications and dual indicators fit your installation.”
DMITIZYN 140V DC 2-Pole Surge Protective Device, 80kA
The DMITIZYN is a practical match for a 140V DC panel serving security or communications equipment, as well as solar installations. Its core ratings—80kA maximum surge current, 40kA nominal discharge current, and ≤3.6kV protection level—closely match the ZDWXMGUY and KIQPEEFK options, so the choice comes down more to documented application and physical fit than to a different protection class. The listed flame-retardant red housing and green indicators add visible identification and status checking inside an enclosure. It uses standard DIN-rail mounting, but the product information does not provide a unique compatibility list or additional features that clearly separate it electrically from its near-identical DC counterparts. Skip it for AC protection or systems above 140V DC, and confirm the ratings suit the installation before selection.
Pros:- 80kA Imax and 40kA In ratings are clearly specified
- Green indicators support quick visual status checks
- DIN-rail format fits standard electrical enclosures
- Flame-retardant red housing is specified
Cons:- Limited to 140V DC systems
- Its core ratings and mounting are similar to the ZDWXMGUY and KIQPEEFK, with few stated differentiators
- The supplied data does not identify a specific compatibility list for security or communications systems
Best for: Panel builders protecting 140V DC solar, security, or communications equipment who value a flame-retardant housing and visible status indication.
Not ideal for: Buyers needing an AC SPD, a protector for DC systems above 140V, or product-specific compatibility documentation beyond the stated general applications.
- Voltage:140V DC
- Poles:2
- Maximum surge current (Imax):80kA
- Nominal discharge current (In):40kA
- Protection level (Up):≤3.6kV
- Mounting:DIN rail
- Standard:GB18802.1-2011 Type 2
- Housing:Flame-retardant red
- Dimensions:2.8 × 3.5 × 4 in (D × W × H)
Our verdict“Pick the DMITIZYN when you need a 140V DC DIN-rail SPD for solar, security, or communications equipment and its stated housing details suit your panel.”
Type 2 Surge Protective Device, 1-Pole, 40–80 kA, 385 VAC
This is the lineup’s AC-oriented alternative, not a direct replacement for the 140V DC ZDWXMGUY, DMITIZYN, KIQPEEFK, or QMOSSUSY. The listing specifies a 385 VAC design and a single pole, making system type and wiring configuration the first compatibility checks; its discharge-current options span 40–80kA, but the supplied product data does not say which configuration is included. A removable module and tool-free guide-rail mounting may make servicing more convenient than a fixed unit, while the flame-retardant shell and red copper terminals are stated construction details. Compared with the DC-focused products, its main advantage is an AC voltage specification and removable design. Its main drawback is uncertainty: confirm the exact current configuration, protection level, and installation requirements before treating it as an 80kA choice.
Pros:- Specified for 385 VAC rather than the 140V DC systems covered by the other listed units
- Removable module can support replacement or servicing
- Tool-free guide-rail mounting is specified
- Flame-retardant shell and red copper terminals are listed
Cons:- The listing gives 40kA, 65kA, and 80kA options without identifying the supplied configuration
- Single-pole design may not suit the required panel wiring arrangement
- Warranty is listed as 90 days
Best for: AC panel installers who need a single-pole Type 2 SPD with a removable module and can confirm the included discharge-current configuration before purchase.
Not ideal for: Buyers protecting 140V DC solar equipment, anyone requiring a confirmed 80kA configuration without further verification, or installations needing a multi-pole device.
- Type:Type 2 surge protective device
- Poles:1P
- Discharge current options:40kA, 65kA, 80kA
- Nominal discharge current options:20kA, 30kA, 40kA
- Mounting:Guide rail; tool-free mounting described
- Weight:Approx. 127g (4.5oz)
- Warranty:90 days
Our verdict“Choose this model for a compatible AC panel only after confirming the supplied current rating and required pole arrangement.”
KIQPEEFK 140V DC 2-Pole Surge Protective Device, 80kA
The KIQPEEFK gives panel planners a clearly stated 140V DC, 2-pole Type 2 format with 80kA maximum and 40kA nominal discharge ratings. Its listed dimensions—2.8 × 3.5 × 4 inches—make it easier to check enclosure space before specifying it, a useful detail for retrofit work where rail and wiring room may be limited. Like the QMOSSUSY and ZDWXMGUY, it adds visual status indication and DIN-rail mounting; the supplied information does not establish a performance advantage over those near-matching devices. The ≤3.6kV protection level and stated standard help define its electrical profile, but buyers still need to confirm coordination with the protected equipment and system. Its “SOLAR PANEL” model name is generic, and the 140V DC ceiling rules out AC or higher-voltage DC applications.
Pros:- Lists dimensions for enclosure-space planning
- 80kA maximum and 40kA nominal discharge currents are stated
- DIN-rail mounting suits panel installations
- Visual indicators provide a status check
Cons:- Designed specifically for 140V DC systems
- The “SOLAR PANEL” model name offers limited product identification
- No stated electrical advantage over similar 140V DC options such as the QMOSSUSY
Best for: Electrical contractors retrofitting a 140V DC enclosure who want stated dimensions, DIN-rail mounting, and visual status indicators.
Not ideal for: AC panel owners, operators of DC systems above 140V, or buyers who need a clearly differentiated model identity or documented application-specific compatibility.
- System voltage:140V DC
- Poles:2
- Maximum discharge current (Imax):80kA
- Nominal discharge current (In):40kA
- Voltage protection level (Up):≤3.6kV
- Mounting:DIN rail
- Standard:GB18802.1-2011 Type 2
- Dimensions:2.8 × 3.5 × 4 in (D × W × H)
Our verdict“Consider the KIQPEEFK for a 140V DC retrofit when its dimensions fit and you can verify system coordination independently.”
QMOSSUSY 140V DC 2-Pole Surge Protector, 80kA
The QMOSSUSY is a straightforward choice for a 140V DC panel where operators want status indication on both poles. It shares the ZDWXMGUY’s 80kA maximum surge current, 40kA nominal discharge current, ≤3.6kV protection level, and DIN-rail format, so its appeal is the specifically described two-pole indicators rather than a distinct surge rating. The listing also describes residential and light-commercial panel use, giving it a more defined setting than the KIQPEEFK’s generic “SOLAR PANEL” model label. That does not confirm compatibility with every DC installation, though: the system’s voltage and protection coordination still need checking. Its 140V DC ceiling excludes AC panels and higher-voltage solar arrays, while the stated 2.8 × 3.5 × 4-inch body may be a constraint in crowded enclosures.
Pros:- Visual status indicators are specified on both poles
- 80kA maximum and 40kA nominal surge-current ratings are stated
- DIN-rail mounting fits electrical panels
- Residential and light-commercial use is identified in the description
Cons:- Limited to DC systems up to 140V
- The product information does not specify compatibility with particular DC systems
- The 2.8 × 3.5 × 4-inch dimensions may challenge tight enclosures
Best for: Residential or light-commercial panel operators with a 140V DC system who want individual visual status indicators for both poles.
Not ideal for: Buyers with AC circuits, DC arrays above 140V, or installations that require confirmed compatibility with a particular system or more compact dimensions.
- Maximum system voltage:140V DC
- Poles:2
- Maximum surge current (Imax):80kA
- Nominal discharge current (In):40kA
- Voltage protection level:3.6kV or less
- Mounting:DIN rail
- Standard:GB18802.1-2011 Type 2
- Dimensions:2.8 × 3.5 × 4 in (D × W × H)
Our verdict“Choose the QMOSSUSY for a compatible 140V DC residential or light-commercial panel when two-pole status visibility is your priority.”
Type 2 Surge Protective Device, 2–4 Pole, 20–100 kA
This is the most adaptable AC choice in this group: its 2-, 3-, or 4-pole options and stated 20–100 kA range let panel planners match the device to different distribution setups. Unlike the 80 kA Type 1 3+1 model, this is a Type 2 device for distribution boxes and control panels, so the protection class and installation context differ rather than serving as a direct substitute. Its DIN-rail mounting suits cabinet builds, but the broad configuration range leaves a buyer needing to confirm the exact pole count, voltage, and surge rating on the selected version. I would choose it when AC panel flexibility matters; I would skip it if a clearly specified 80 kA configuration is a requirement.
Pros:- Offers 2-, 3-, and 4-pole configurations
- Listed surge capacity range includes 80 kA
- DIN-rail mounting suits distribution boxes and control panels
- Designed for 220 V or 380 V AC systems
Cons:- The listing does not identify which specific configuration is supplied
- Broad capacity range makes the exact rating unclear without checking the selected version
- Does not list remote signaling or a protection-level figure
Best for: Panel builders selecting a Type 2 AC device for a 220 V or 380 V distribution box who can verify the exact pole and capacity configuration before purchase
Not ideal for: Buyers who need a clearly identified 80 kA rating or a Type 1 device with remote status signaling
- Protection type:Type 2
- Poles:2P, 3P, or 4P
- Surge capacity:20–100 kA
- System voltage:220 V or 380 V
- Mounting:DIN rail
- Applications:Distribution boxes and control panels
- Package quantity:1
Our verdict“Choose this Type 2 model for configurable AC panel layouts, but verify the exact rating and pole count before ordering.”
80 kA Type 1 Surge Protective Device with Remote Signaling, 3+1, 220/380 V
Among these options, this is the clearest fit for buyers seeking 80 kA protection on a three-phase AC system: it specifies Type 1 protection, a 3+1 arrangement, 220/380 V compatibility, and a protection level of ≤ 2.2 kV. The standout difference from the Type 2 2–4 pole model is its remote signaling, which can feed device status to a monitoring setup instead of relying only on a cabinet inspection. That added monitoring focus comes with a narrower use case: it is a four-module, three-phase arrangement, not a flexible DC protector like the 1000 V model. Buyers should also confirm system and installation requirements with a qualified electrician; the listing does not provide detailed wiring guidance.
Pros:- Specifies 80 kA maximum discharge current
- Remote signaling supports status monitoring
- 3+1 configuration is listed for 220/380 V three-phase systems
- Protection level is specified as ≤ 2.2 kV
Cons:- Four-module layout may require more DIN-rail space than simpler configurations
- The stated 3+1 configuration is not a flexible option for every panel layout
- The listing provides limited installation and wiring detail
Best for: Facility and control-panel operators with 220/380 V three-phase systems who want remote indication of surge-device status
Not ideal for: Solar or other DC-system owners, and buyers seeking a Type 2 device or a compact single-phase configuration
- Protection class:Class I, Type 1 (Level B)
- Maximum discharge current:80 kA (8/20 μs)
- Voltage:220/380 V
- Configuration:3+1, three-phase
- Protection level:≤ 2.2 kV
- Modules:4
- Mounting:35 mm rail
- Special feature:Remote signaling
Our verdict“Pick this for a monitored 220/380 V three-phase installation where Type 1 protection and remote status matter.”
THPHNB 140V DC 2-Pole 80kA Surge Protector
The THPHNB is presented as an 80 kA, 140 V DC protector for household and industrial distribution cabinets, which could suit a buyer whose circuit matches those stated conditions. But it is harder to select confidently than the CKIOEVZ model: the pole count conflicts, with 2 poles in the title and 1 in the specification, and the supplied information does not establish broader voltage compatibility. Its guide-rail installation claim points toward cabinet use, while the listed bolt-on mount adds further ambiguity about the actual mounting format. I would put it behind the better-defined 80 kA Type 1 AC unit for buyers who need a specified system configuration. Proceed only after confirming pole count, mounting, and circuit compatibility from the seller.
Pros:- Advertised for 140 V DC circuits
- States an 80 kA surge capacity
- Intended for household and industrial distribution cabinets
Cons:- Pole count differs between the title and specification listing
- Mounting information conflicts between guide-rail description and bolt-on specification
- Compatibility details beyond conventional distribution boxes are limited
Best for: Electrical buyers with a 140 V DC distribution circuit who can confirm the actual pole count and mounting method before installation
Not ideal for: Installers who need dependable, internally consistent pole and mounting specifications to finalize a panel design
- Brand:THPHNB
- Model:80KA
- Input voltage:140 V DC
- Poles:2 in title; 1 in specification listing
- Mounting information:Guide-rail installation described; bolt-on mount listed
- Circuit breaker type:Standard
- Certification:CE, NONE
- Origin:China
Our verdict“Consider this only for a confirmed 140 V DC application after resolving the pole-count and mounting discrepancies.”
CKIOEVZ 140V DC 2-Pole 80kA Surge Protector
The CKIOEVZ offers a practical cabinet-oriented feature set: DIN-rail mounting, a visible status indicator, and a built-in thermal cutoff. Those details give it a clearer day-to-day monitoring story than the THPHNB, whose pole and mounting descriptions conflict. Still, this is not an easy specification to approve: the title states 140 V DC, while the description gives a limit below 75 V DC and also mentions below 50 V AC. That contradiction affects the most basic fit question, so I would not treat the advertised voltage as confirmed. The listed 80 kA capacity and two-pole format may attract DC-cabinet buyers, but they should first obtain authoritative compatibility data.
Pros:- Built-in thermal cutoff is specified
- Visible status indicator supports quick cabinet checks
- Standard DIN-rail mounting is listed
- Two-pole configuration and 80 kA capacity are stated
Cons:- Voltage information conflicts between the title and description
- Material is listed as plastic without further construction details
- The listing does not resolve which circuit voltage range is supported
Best for: DC-cabinet owners who value a visible status window and thermal cutoff and can verify the permitted operating voltage
Not ideal for: Installers who need an unambiguous voltage rating for a 140 V DC circuit before selecting protection
- Brand:CKIOEVZ
- Voltage:140 V DC in title; below 50 V AC or 75 V DC in description
- Poles:2
- Surge capacity:80 kA
- Installation:DIN rail
- Material:Plastic
- Quantity:1
- Features:Thermal cutoff and visible status indicator
Our verdict“Choose this only after confirming the voltage rating, since its status indicator and cutoff do not offset the conflicting compatibility details.”
80 kA 1000 V DC Surge Protective Device, 3-Pole DIN Rail Mount
For a high-voltage DC panel, this is the most clearly targeted option in the lineup: it specifies up to 1000 V DC, three poles, an 80 kA maximum discharge current, and a 40 kA nominal discharge current. That makes it a different proposition from the 140 V DC CKIOEVZ and THPHNB devices, whose voltage details are less suitable or less clear for a high-voltage solar array. The 35 mm DIN-rail mount, visual indicator, and stated 25 ns response time add useful installation and status details. The tradeoff is its IP20 enclosure rating, which calls for protected indoor placement, plus inconsistent package-content wording. Verify the included components and system design before fitting it.
Pros:- Rated for DC circuits up to 1000 V
- Lists both 80 kA maximum and 40 kA nominal discharge currents
- Visual status indicator helps identify device condition
- 35 mm DIN-rail mounting and stated 25 ns response time
Cons:- IP20 rating limits suitability for exposed environments
- Package-content wording is inconsistent
- Three-pole configuration may not match every DC panel design
Best for: Solar and control-panel installers needing a specified 1000 V DC, three-pole surge protector for a protected cabinet
Not ideal for: Buyers installing outdoors or in exposed locations, or those seeking protection for low-voltage 140 V DC circuits
- Maximum discharge current:80 kA
- Nominal discharge current:40 kA
- Maximum voltage:1000 V DC
- Protection level:2.2 kV
- Response time:25 ns
- Mounting:35 mm DIN rail
- Recommended wire connection:4–25 mm²
- Ambient temperature:-40°C to +80°C
Our verdict“This is the strongest fit here for a protected high-voltage DC or solar cabinet, provided the three-pole layout and package contents match the installation.”
How We Picked
I ranked these products by how clearly their stated specifications map to a buyer’s panel and electrical system. The main criteria were AC or DC compatibility, rated operating voltage, pole count, stated surge-current rating, protection type, mounting information, and useful operational features such as remote signaling. A high current figure only helps when the device also fits the system voltage, grounding arrangement, and installation layout.
The ZDWXMGUY leads as the clearest all-around match for the roundup’s 80 kA focus and a specifically stated 140 V DC, 2-pole use case. Other products rank higher for narrower needs—such as remote status reporting or 1000 V DC service—or lower when the listing gives a broad range or fewer application details. Several near-identical 140 V DC listings cannot be reliably separated by their names alone, so I treat their documentation and certification as a deciding factor rather than inventing performance differences.
Factors to Consider When Choosing Panel Mount Spd 80 Ka
Before selecting an 80 kA SPD for a panel, match the device to the electrical system and installation—not just the headline rating. These checks help prevent a common buying mistake: choosing a product with an appealing surge figure that is not suitable for the panel it must protect.
Match the SPD to AC or DC service and system voltage
Start with the nominal voltage and whether the circuit is AC or DC; those details rule out many otherwise similar-looking devices. A 140 V DC unit is not a substitute for a 385 V AC SPD, and a 1000 V DC device belongs to a different application class. Check the device’s maximum continuous operating voltage against the system’s actual operating range, including expected variation. Do not infer compatibility from a product title or from the 80 kA number. When a listing omits a clear datasheet, pause and ask the supplier for the exact electrical ratings before selecting it.
Read the surge rating in context
An 80 kA rating needs a defined test and rating context to support a meaningful comparison. Product titles may not say whether the figure describes a particular surge-current measure, per-pole capacity, or another test condition. Compare the full datasheet and applicable standards, not only the largest number in a listing. Also check the device’s voltage protection level and other relevant ratings against the equipment being protected. Paying extra for a larger headline figure may offer little benefit if the rest of the device’s specifications are unsuitable for the installation.
Choose poles and protection type for the circuit
Pole count must suit the conductors and grounding arrangement the SPD is intended to protect. The lineup includes 1-pole, 2-pole, 3-pole, and 3+1 configurations, which serve different wiring setups rather than representing a simple quality ladder. Type 1 and Type 2 also indicate different installation roles; confirm the required type with the panel design and applicable electrical rules. Do not assume a 2-pole DC unit can replace a multi-pole AC product because both carry an 80 kA label. If you are uncertain about the arrangement, have a qualified electrician verify the panel configuration before purchase.
Confirm mounting, enclosure fit, and installation details
The phrase panel mount does not guarantee a particular mounting method. Check whether the product is designed for DIN-rail installation or another panel arrangement, and confirm its dimensions, terminal layout, wire range, and required clearances. A device that fits electrically can still be impractical if it cannot be installed in the available enclosure space. Look for wiring diagrams and installation instructions before choosing between compact-looking or multi-pole options. Leave room for safe conductor routing and follow the manufacturer’s stated installation requirements rather than modifying the panel to accommodate an uncertain listing.
Weigh status monitoring against a simpler installation
Remote signaling can help a facility identify an SPD condition without opening a panel, which may be useful when equipment is hard to access or downtime is costly. The remote-signaling Type 1 option is the only listing here that specifically calls out that capability. Confirm what the signal reports, how it connects to the monitoring system, and whether the contact type suits the control circuit. For a small installation with direct visual access, the added wiring and integration may not be worthwhile. Buy the feature for a real monitoring need, not simply because it sounds more advanced.
Verify documentation, certification, and replacement planning
Several products have near-identical names and headline specifications, so manufacturer documentation can be the deciding factor. Request datasheets that identify applicable standards, electrical ratings, wiring, status indication, and replacement procedure. Confirm the exact model number and required approvals for the location and jurisdiction; do not assume that a marketplace description establishes compliance. Consider how the device signals end of life and whether replacement modules or compatible units are available. A cheaper or less-documented option can cost more in installation uncertainty if its ratings cannot be verified.
Frequently Asked Questions
Can I choose an 80 kA SPD by surge rating alone?
No. The rating is only one part of the match, and product listings may not explain the test basis or how the figure applies to each pole. Confirm AC or DC service, operating voltage, pole configuration, protection type, and the full datasheet ratings. Check that the device suits the panel’s wiring and the equipment it is meant to protect. If a listing does not provide this information, do not treat the 80 kA headline as proof of compatibility.
Are the six 140 V DC, 2-pole, 80 kA products interchangeable?
Their titles describe a similar stated application, but that is not enough to confirm they are interchangeable. Compare exact model numbers, continuous operating voltage, surge test ratings, protection level, certifications, terminal details, and mounting instructions. Differences may appear in the datasheets even when the product names look alike. If the manufacturer does not provide verifiable specifications, I would choose a better-documented option or request clarification before installation.
Should I choose the Type 1 remote-signaling SPD or a Type 2 model?
Choose based on the installation role specified by the electrical design, not on the added signaling feature alone. Type 1 and Type 2 devices are intended for different positions or protection arrangements, and the required type depends on the system and applicable rules. Remote signaling can help report device status, but it does not make a Type 1 model a replacement for a required Type 2 unit, or vice versa. Confirm the 220/380 V configuration and the signal interface with the system documentation and a qualified installer.
Is the 1000 V DC, 3-pole SPD a better choice than a 140 V DC unit?
Not unless the installation calls for its higher DC voltage and 3-pole arrangement. A higher voltage rating is not a general performance upgrade, and installing a device with the wrong operating characteristics can leave the system poorly protected. Compare the SPD’s working voltage and protection level with the DC system design, then confirm pole use and mounting. For a 140 V DC, 2-pole circuit, the similarly specified 140 V options are the more directly relevant candidates.
What should I verify before ordering a panel-mount SPD from a listing with limited details?
Ask for the manufacturer’s datasheet and installation instructions, then confirm the exact model, voltage, AC or DC rating, pole count, surge-rating definition, and protection type. Verify applicable approvals, enclosure dimensions, mounting method, terminal capacity, and wiring diagram. For remote signaling, request the contact specification and status behavior as well. If those points cannot be confirmed, the product title alone is not a sound basis for choosing a protective device; consult a qualified electrician or the manufacturer.
Conclusion
Best overall: I’d start with the ZDWXMGUY 140 V DC, 2-pole SPD for buyers whose system matches those stated specifications and who want a direct 80 kA option. Best value: compare the six similarly specified 140 V DC models by documentation, approvals, and mounting details, since their titles alone do not establish a meaningful difference. Best premium or monitoring-focused choice: the 80 kA Type 1 model with remote signaling is the clearest fit when its 220/380 V configuration and monitoring interface suit the panel. Best for beginners: choose the best-documented model that matches the panel exactly, and have an electrician confirm compatibility rather than relying on a headline rating. Best for specific needs: consider the 385 V AC product for a compatible AC system or the 1000 V DC, 3-pole unit for an appropriate high-voltage DC application. My final choice would depend on the datasheet and installation requirements; none of these devices should be selected by kA rating alone.
