Description
Square D by Schneider Electric Surge Protection Device (SPD) for home appliances, distribution panels, and HVAC equipment, 25kA, 120/240V Input, Single Phase
Square D by Schneider Electric Home Electronics Protective Device (HEPD25)
The Square D HEPD25 (Home Electronics Protective Device) by Schneider Electric is a compact, whole-home Type 1 and Type 2 Surge Protective Device (SPD). Engineered to safeguard sensitive residential appliances, microprocessors, and smart-home electronics against transient electrical surges, the HEPD25 offers a 25kA surge current capacity per phase, universal panel compatibility across any electrical brand, and a rugged NEMA 4X outdoor-rated enclosure suitable for indoor load centers or exterior subpanels.
Key Features & Performance Benefits
- Whole-Home Surge Suppression: Protects modern appliances, HVAC circuits, home automation equipment, and entertainment systems from both external utility transients and internal inductive switching spikes.
- Dual Type 1 & Type 2 Certification: Approved for installation line-side (ahead of the main disconnect as Type 1) or load-side (downstream on a dedicated 2-pole breaker as Type 2).
- Universal Brand Compatibility: Nipple-mount design connects via a standard 1/2-inch knockout to any manufacturer's load center (Square D QO/Homeline, Siemens, Eaton, GE, Leviton).
- Visual Operational LED: Green diagnostic LED confirms continuous active surge suppression capability; if extinguished, it alerts the homeowner that the internal MOV circuitry has sacrificed itself.
- Weatherproof NEMA 4X Enclosure: Sealed non-metallic casing allows installation inside interior basements or utility closets, as well as exterior locations alongside meter combos or outdoor air handler disconnects.
- Short Circuit Current Rating (SCCR): Tested to 22kA SCCR, providing coordination with standard residential residential breaker panels.

Frequently Asked Questions
What does "HEPD25" stand for in Square D's catalog?
"HEPD" stands for Home Electronics Protective Device, and "25" designates its surge current capacity rating of 25 kA per phase (50 kA total surge capacity).
How does the HEPD25 differ from the HEPD50 and HEPD80?
The primary difference is surge current capacity per phase. The HEPD25 is rated for 25 kA per phase, the HEPD50 is rated for 50 kA per phase, and the HEPD80 is rated for 80 kA per phase. Higher ratings provide greater durability and extended life expectancy when handling repeated surge events.
Can the HEPD25 be installed on non-Square D panels?
Yes. Because the HEPD25 is an externally mounted, hardwired unit that mounts through a standard 1/2" knockout, it is universally compatible with any brand of electrical panel, including Eaton, Siemens, GE, and Leviton.
What does it mean if the green indicator LED is off?
The green LED signifies active surge suppression. If the light is unlit, verify that the dedicated 2-pole breaker feeding the unit is switched ON. If the breaker is energized and 240V is present across the black leads, an extinguished LED indicates the internal MOVs have absorbed a catastrophic surge and the unit must be replaced.
