More Details on Our Top Picks
Square D by Schneider Electric HOM2175SB Homeline SurgeBreaker Surge Protection Device 25kA 120/240V
This surge protector excels at safeguarding circuits within existing load centers, making it a practical choice for homeowners with Homeline panels. Compared to the Square D HEPD80, which protects the entire home, the SurgeBreaker offers targeted circuit protection, ideal for those who want to add surge defense to specific circuits without replacing the main panel. Its plug-on design simplifies installation, but it requires 2 spaces in your load center and is limited to 1-phase systems. For apartments with Homeline panels, it provides an affordable, straightforward upgrade, though it’s less versatile outside that system. The tradeoff lies in its limited scope and the need for compatible panels.
Pros:- Easy plug-on installation
- Provides reliable circuit-level surge protection
- LED indicator for status monitoring
Cons:- Requires 2 spaces in the load center
- Limited to 1-phase systems
- Restricted to Homeline panels only
Best for: Homeowners or apartment residents with Homeline load centers seeking targeted circuit surge protection.
Not ideal for: Users with non-Homeline panels or those wanting whole-house protection without panel modifications.
- Protection Rating:25kA
- Voltage:120/240V
- Phase:1-Phase
- Wire:3-Wire
- Installation:Plug-on
- UL Listing:UL 1449 3rd Edition
