A home surge protection system can help limit damaging voltage spikes before they reach household circuits, but the right choice depends on your panel, installation point, and protection needs. My best overall pick is the Square D HEPD80, which pairs a stated 80kA rating with clearly specified 120/240V, single-phase service. The Eaton Complete Home is a Type 2 option with a 60kA rating, while the FHSPD108S has the highest stated surge-current figure in this group. The main tradeoffs are Type 1 versus Type 2 installation, panel compatibility, and whether a higher advertised rating fits your needs. Read on for the full comparison and a guide to choosing a device that matches your home.

Key Takeaways
- Square D HEPD80 is my overall pick because its 80kA rating and 120/240V, single-phase, three-wire specifications make its stated fit easy to evaluate.
- The FHSPD108S has the highest listed surge-current rating at 108,000 amps, but that number alone does not establish how well it will suit a particular panel or installation.
- Type 1 and Type 2 devices are not interchangeable by default. The HSPD-25 and ABB are identified as Type 1, while the Eaton Complete Home is identified as Type 2; installation location and code requirements matter.
- Panel fit can outweigh headline capacity. The Type BR breaker surge device is the panel-specific choice in this lineup, so it only makes sense when the electrical panel is compatible.
- The lineup spans a wide range of stated ratings. Furniqro FHSPD36S lists 36,000 amps, while Square D HEPD80 lists 80kA and FHSPD108S lists 108,000 amps; compare ratings alongside device type and installation requirements.

More Details on Our Top Picks
Type BR Circuit Breaker Surge Protective Device, Two Pole
This two-pole surge-protective breaker makes the most sense when your home already has a compatible Type BR panelboard and you want a panel-based option rather than a plug-in strip. Its stated purpose is to protect appliances and electronics from voltage spikes and transient surges, but the available product details do not give a surge-capacity figure or monitoring indicator. That makes it harder to compare its protection level with the Square D HEPD80, which lists an 80kA capacity and LED status indicator. The BR model’s narrower panel compatibility is a real constraint, yet may suit owners who want a device matched to their existing equipment. I would choose it only after confirming panel compatibility and getting installation guidance from a qualified electrician.
Pros:- Designed to fit standard Type BR panelboards
- Two-pole format provides a panel-based protection option
- Targets appliances and electronics exposed to voltage spikes and transient surges
Cons:- No surge-capacity figure is provided, making protection comparisons difficult
- Compatibility is limited to Type BR panelboards
- The available details do not specify monitoring features or installation requirements
Best for: Homeowners with a compatible Type BR panelboard who want a panel-mounted surge-protection device and can confirm fit before installation.
Not ideal for: Owners of non-Type BR panels or buyers who want a published surge-capacity rating and status indicator for comparison.
- Type:BR
- Poles:Two pole
- Function:Surge protective device

Our verdict“Choose this breaker-style option if you have a compatible Type BR panel and can verify its fit and protection details with an electrician.”
HSPD-25 Type 1 Whole Home Surge Protective Device (120/240VAC)
The HSPD-25 stands out for buyers seeking a Type 1 whole-home device with broad breaker compatibility and a stated 25kA surge capacity. Its indoor-and-outdoor installation rating offers more placement flexibility than a device specified only for a residential load center, while the compact design may help where panel space is limited. Compared with the Square D HEPD80, it lists a lower surge-capacity figure and does not specify an LED status indicator; the Square D provides more information for buyers prioritizing capacity and monitoring. The HSPD-25’s U-SPM module is described as absorbing voltage spikes, but installation may call for professional electrical help. I’d favor it when universal compatibility and installation flexibility matter more than the highest listed capacity.
Pros:- Type 1 design is intended for whole-house surge protection
- Lists surge capacity up to 25kA
- Compatible with circuit breakers from any brand
- Rated for indoor and outdoor installation
Cons:- Its listed capacity is lower than the Square D HEPD80’s 80kA figure

Square D HEPD80 Whole House Surge Protection Device, 80kA, 1-Phase, 3-Wire, 120/240V
The HEPD80 is the clearest choice here for shoppers who want a prominently stated 80kA surge capacity and a way to check device status at a glance. Its 120/240V, single-phase, three-wire specification is aimed at residential load centers, and the LED indicator gives homeowners a visible signal about protection status. Against the HSPD-25, the Square D lists a substantially higher capacity, though the HSPD-25 offers indoor-and-outdoor installation and universal breaker compatibility. That makes the HEPD80 a more defined fit for a residential panel, not automatically the right match for every setup. The tradeoff is that installation belongs with a qualified professional, and this panel device does not replace point-of-use strips for sensitive electronics.
Pros:- Lists an 80kA surge capacity
- LED indicator provides a visible status check
- Specified for residential load centers and 120/240V service

Our verdict“Choose the HEPD80 if your residential panel is compatible and you value its 80kA listed capacity and LED status check.”
Furniqro FHSPD36S Whole House Surge Protector (36,000 Amps, 120/240V)
The FHSPD36S pairs a stated 36,000-amp capacity with indoor-or-outdoor installation and LED status indicators, giving buyers a useful mix of placement flexibility and at-a-glance monitoring. That combination sets it apart from the Eaton CHSPT2ULTRA, whose listed details focus on universal load-center compatibility but do not provide a capacity figure or indicator. By comparison, the Square D HEPD80 lists 80kA, so the Furniqro’s stated capacity is lower for shoppers using those published figures as a sorting tool. It is described as compatible with major load-center and breaker brands, which can ease fit checks, but it still calls for electrician-level installation. The lack of a stated warranty is another reason to weigh it against options with clearer ownership details.
Pros:- Lists surge protection up to 36,000 amps
- Can be installed indoors or outdoors
- LED indicators show protection status
- Compatible with major load-center and circuit-breaker brands
Cons:- Lists a lower capacity than the Square D HEPD80’s 80kA figure

- Installation location:Indoor or outdoor
- Compatibility:All brands of load centers and circuit breakers
- Status indicator:LED
Our verdict“The FHSPD36S suits buyers who value flexible placement and LED monitoring, provided its listed capacity and unspecified warranty meet their needs.”
Eaton CHSPT2ULTRA Surge Protection Device, 1 Phase, 120/240V, 2 Poles
The Eaton CHSPT2ULTRA is a practical fit-first choice: its universal load-center compatibility makes it appealing when the panel brand is the main hurdle. It is specified for single-phase, 120/240V, two-pole systems, and the description presents installation as easy. Still, panel work should be handled by someone qualified to work safely with electrical equipment. Compared with the HSPD-25, Eaton shares broad compatibility but does not list a surge-capacity figure or indoor/outdoor rating in the supplied details. That makes it harder to judge protection strength and placement options before buying. I’d shortlist it for a straightforward compatibility match, but choose the Square D HEPD80 instead if a published capacity and LED status indicator matter more than a universal fit claim.
Pros:- Compatible with any manufacturer’s load center
- Specified for 120/240V systems
- Two-pole, single-phase configuration is clearly stated
- Described as easy to install
Cons:- No surge-capacity figure is provided in the available details

Eaton Complete Home Surge Protector, Type 2 SPD, 60kA Surge Current
For homeowners seeking a hardwired panel-mounted layer, the 60kA surge-current capacity gives this Eaton a clear role among Type 2 options. Its weather-resistant housing supports indoor or outdoor installation, while LED status indicators make protection status easier to check at a glance. Compared with the ABB THOMESURGEP, this is a Type 2 device rather than a Type 1 model intended for service-entrance use, so the installation context matters as much as the capacity figure. It also has a higher stated surge-current capacity than the ABB’s 36kA per phase. The tradeoff is that this unit requires hardwiring at the electrical panel, and its pre-attached leads may call for an electrician rather than a simple homeowner setup.
Pros:- 60kA surge-current capacity for whole-home protection
- Weather-resistant housing supports indoor or outdoor installation
- LED indicators provide a visible status check
- UL Listed and NEC compliant
Cons:- Requires hardwired installation at the electrical panel
- Pre-attached leads may require an electrician for correct setup
Best for: Homeowners looking for a higher-capacity Type 2 SPD with indoor/outdoor placement and visible status monitoring
Not ideal for: DIY buyers who want a plug-in or breaker-space installation, since this device is hardwired and may require professional electrical work
- Type:Type 2 SPD
- Surge current:60kA
- Nominal discharge:10kA
- Installation:Hardwired; indoor or outdoor
- Certifications:UL Listed; NEC compliant
- Status indicators:LED
Our verdict“Choose this Eaton if you want a 60kA Type 2 SPD with status lights and can arrange a proper hardwired installation.”
ABB THOMESURGEP Whole Home Surge Protection Device, Type 1 SPD, NEMA 3R
The ABB THOMESURGEP stands apart through its Type 1 design for service entrances or sub-panels, making installation position its key distinction from the Eaton Complete Home Type 2 SPD. It provides 36kA per phase and meets NEC 2023 Article 230.67 requirements listed for new construction and renovations. Its contractor-friendly installation does not use breaker spaces, which can help when a load center has little room to spare. The 200kA SCCR is another specified electrical rating, though it should not be confused with surge-current capacity. Compared with the FHSPD108S, the ABB offers a more clearly defined service-entrance role, while the FHSPD108S advertises a higher overall surge-current figure. Professional installation is a real tradeoff, and its voltage compatibility is based on US electrical systems.
Pros:- Type 1 design suits service-entrance and sub-panel applications
- 36kA surge protection per phase
- Installs without occupying breaker spaces
- Specified compliance with NEC 2023 Article 230.67
Cons:- Service-entrance installation calls for a professional
- Voltage specifications are for US electrical systems
- Its stated 36kA per phase is lower than the 60kA figure listed for the Eaton Type 2
Best for: Homeowners, builders, and renovators planning a service-entrance or sub-panel installation that needs NEC 2023 Article 230.67 compliance
Not ideal for: Buyers who need a DIY installation or want a device specified for international electrical systems

- SCCR:200kA
- Frequency:50–60Hz
- Compliance:NEC 2023 Article 230.67
Our verdict“Pick the ABB when Type 1 placement, code-related project requirements, and saved breaker space matter more than a higher stated surge-current figure.”
FHSPD108S Whole House Surge Protector (108,000 Amps, 120/240V)
The FHSPD108S leads this group on its stated 108,000-amp surge capacity, making it the pick for buyers who prioritize that headline specification. Its compact form and commercial-grade enclosure allow indoor or outdoor installation, and the maker lists compatibility with any brand of load centers and circuit breakers. That broad compatibility contrasts with the ABB THOMESURGEP, whose standout advantage is its Type 1 service-entrance role and no-breaker-space installation. The Eaton Complete Home SPD is another alternative, with a lower stated 60kA capacity but specified UL listing and NEC compliance. The FHSPD108S provides LED indicators, but the supplied specifications do not list a certification or SPD type. Professional installation and correct grounding matter here; the product description warns that improper grounding or misuse can cause startup issues.
Pros:- 108,000-amp stated surge-current capacity
- Compact design for installation where space is limited
- Commercial-grade enclosure for indoor or outdoor use
- Listed as compatible with any brand of load centers and circuit breakers

- Surge-current capacity:108,000 amps
- Voltage:120/240V
- Frequency:60Hz
- Installation location:Indoor or outdoor
- Compatibility:Any brand of load centers and circuit breakers
- Status indicators:LED
Our verdict“Choose the FHSPD108S if its high stated capacity and broad panel compatibility suit your setup and you can have it professionally installed.”
How We Picked
I compared the eight devices using the details provided for each model: surge-current rating, device type, voltage and phase information, pole configuration, enclosure details, and panel-specific fit. I gave more weight to options with clear specifications that help a buyer check service compatibility, while treating a larger amp figure as one data point rather than proof of better real-world protection. Type 1, Type 2, and breaker-style products serve different installation situations, so I did not rank them as if they were direct substitutes.
That logic puts the Square D HEPD80 first for its clearly stated electrical specifications and 80kA rating. The FHSPD108S stands out for its higher listed rating, and the ABB’s Type 1 designation and NEMA 3R enclosure give it a distinct role. The Type BR unit ranks as a specialist option because panel compatibility narrows its audience; the Furniqro FHSPD36S is a more modest-rated choice. Product names and supplied specifications do not establish compatibility with every home, installation quality, or code compliance, so I treat those as buyer checks rather than assumed benefits.

Factors to Consider When Choosing Home Surge Protection System
Choosing a whole-home surge protector takes more than comparing the largest number on the label. I would start with the electrical service and installation location, then check how the device’s type, rating, and enclosure match the home and local requirements.
Match the Device Type to the Installation Point
Type 1 and Type 2 describe different installation roles, not a simple good-better ranking. Type 1 devices are generally intended for connection at the service entrance, while Type 2 devices are generally installed on the load side of the service equipment; the permitted location depends on the product instructions and applicable electrical rules. A common mistake is buying by type name alone without asking where the device can be installed in the existing setup. I would have an electrician identify the suitable location before choosing between options such as the Type 1 HSPD-25 or ABB and the Type 2 Eaton Complete Home. The correct match is the device that fits the installation plan, not automatically the one with the larger rating.
Check Panel Compatibility Before Comparing Ratings
Panel and breaker compatibility can rule out a device immediately, even when its specifications look appealing. The Type BR breaker surge device is the clearest example in this lineup: its format points buyers toward a matching panel family, not universal use. Check the panel label and manufacturer documentation rather than relying on appearance or a seller’s broad compatibility claim. Also confirm available breaker positions, wiring requirements, and whether the device’s voltage and phase match the home’s service. I would make compatibility the first filter, then compare surge-current ratings among the products that remain.
Read Surge-Current Ratings as One Part of the Picture
A higher listed amp rating is useful for comparison, but it does not tell the whole story about a surge protector’s suitability. This roundup ranges from the Furniqro FHSPD36S at 36,000 amps to the FHSPD108S at 108,000 amps, with the Square D HEPD80 listed at 80kA. Before treating these figures as a direct performance ranking, confirm that the manufacturer states them on the same basis and review other published specifications. Buyers can overfocus on the largest number and miss device type, installation limits, or compatibility. I would use the rating to narrow choices only after confirming those basic fit requirements.
Consider Enclosure and Exposure
Where the device will sit affects which enclosure details matter. The ABB THOMESURGEP is identified as a Type 1 SPD with a NEMA 3R enclosure, a relevant distinction for installations exposed to outdoor conditions. Do not assume every whole-home device is suitable for exterior mounting just because it protects the home’s electrical system. Check the exact product instructions for permitted locations, wiring, and environmental limits, then have the installer verify the mounting plan. Paying attention to enclosure type can prevent a mismatch that a surge-current figure will not reveal.
Plan for Installation, Inspection, and Replacement
Whole-home surge protection is an electrical installation decision, not just a device purchase. A licensed electrician can check the panel, service configuration, local rules, and whether the chosen model can be installed as directed. Ask how the unit signals that protection has been reduced or lost, and what maintenance or replacement checks the manufacturer specifies; do not assume all indicators work the same way. A frequent mistake is to choose a device and only afterward discover that the panel or installation point is unsuitable. I would include the installation and future-check plan in the decision, especially when comparing a breaker-style product with a separate SPD.
Frequently Asked Questions
Should I choose a Type 1 or Type 2 whole-home surge protector?
The choice depends on the intended installation point and the product’s approved use, not on a universal ranking between the types. Type 1 devices are generally associated with the service entrance, while Type 2 devices are generally installed on the load side of service equipment. In this lineup, the HSPD-25 and ABB are labeled Type 1, and the Eaton Complete Home is labeled Type 2. Ask an electrician which position is appropriate for your service and check the device instructions and local electrical rules before buying.
Does the FHSPD108S protect better than the Square D HEPD80 because its rating is higher?
Its stated 108,000-amp rating is higher than the Square D HEPD80’s 80kA figure, but that alone does not prove it is the better match or establish a direct performance comparison. Verify how each manufacturer defines and tests the rating, along with the device type, voltage, and installation requirements. Panel compatibility and correct installation can matter more to your decision than the largest printed number. I would treat the FHSPD108S as the higher-rated option on the supplied figures, not as an automatic upgrade for every home.
Can I install a whole-home surge protector myself?
Many whole-home units connect to electrical service equipment, where incorrect installation can create serious shock, fire, or equipment risks. Some products may appear to fit a breaker position, but that does not confirm the panel is compatible or that the installation meets local requirements. Check the manufacturer’s instructions and consult a licensed electrician about the specific model and service panel. I would not choose a device on the assumption that its form factor makes it a safe do-it-yourself project.
How do I know whether the Type BR surge device fits my panel?
Check the panel’s manufacturer and exact model information on its label, then compare that information with the surge device’s compatibility documentation. A Type BR designation is a reason to verify panel-family fit, not a guarantee that the unit works in every panel with a similar-looking breaker. Confirm that the required breaker position and wiring arrangement are available as well. If the documentation is unclear, ask an electrician or the manufacturer before ordering.
Do I still need plug-in surge protectors if I install whole-home protection?
A whole-home device and a plug-in protector serve different points in the electrical system, so one does not automatically replace the other for every setup. Buyers with sensitive electronics may want to ask an electrician whether additional point-of-use protection makes sense for those devices. Check that any plug-in units are suitable for their intended equipment and follow their instructions. I would decide based on the equipment being protected and the advice of the installer, rather than assuming the whole-home unit covers every need on its own.
Conclusion
For the best overall balance of stated specifications, I recommend the Square D HEPD80. Choose the FHSPD108S as the premium, highest-listed-rating option if its installation details and panel fit check out; its larger number should not be the only reason to buy it. For a more modest stated rating, the Furniqro FHSPD36S is the value-oriented pick, while buyers who want a named Type 2 option can compare the Eaton Complete Home. Beginners should start with an electrician’s panel and installation check before settling on a model, rather than treating any product as a universal plug-in choice. For a Type 1 installation with an enclosure detail called out, look closely at the ABB THOMESURGEP; for a breaker-style solution, consider the Type BR device only when the panel is compatible. The right choice is the one that fits your electrical service and installation plan, not simply the one with the biggest amp figure.
