Description
Square D by Schneider Electric HEPD80 Surge Protection Device (SPD) for home appliances, distribution panels, and HVAC equipment, 80kA, 120/240V Input, Single Phase, 3-Wire
Square D by Schneider Electric Home Electronics Protective Device (HEPD80)
The Square D HEPD80 (Home Electronics Protective Device) by Schneider Electric is a top-tier, whole-home Type 1 and Type 2 Surge Protective Device (SPD). Engineered to deliver maximum surge suppression for sensitive electronics, modern smart appliances, HVAC equipment, and variable-speed motor drives, the HEPD80 offers a robust 80kA surge current capacity per phase, universal panel compatibility, and a weatherproof NEMA 4X rated enclosure suited for both indoor load centers and harsh outdoor electrical panels.
Key Features & Performance Benefits
- Maximum Whole-Home Surge Capacity: Provides 80kA peak surge suppression per phase to absorb severe utility surges, direct lightning secondary effects, and internal inductive spikes, offering extended operational life compared to lower-rated units.
- Dual Type 1 & Type 2 Listing: UL 1449 4th Edition listed for mounting ahead of the main service disconnect (Type 1, without a dedicated breaker) or downstream on the load side (Type 2, fed by a 2-pole 15A or 20A breaker).
- Universal Panel Compatibility: External nipple-mount construction connects through any standard 1/2-inch knockout, making it universally compatible with any electrical panel brand (Square D QO & Homeline, Siemens, Eaton, GE, Leviton).
- Dual Phase Diagnostic LEDs: Two green status LEDs monitor protection readiness on each line independently, immediately alerting homeowners if internal MOV components have absorbed a fatal surge.
- Weatherproof NEMA 4X Construction: Corrosion-proof, non-metallic housing rated for indoor load centers or exterior installations such as service entrance panels and outdoor HVAC disconnects.
- Short Circuit Current Rating (SCCR): Tested to 25kA SCCR for safe coordination with residential and light commercial electrical distribution networks.

Frequently Asked Questions
What does "HEPD80" stand for in Square D's catalog?
"HEPD" designates Home Electronics Protective Device, and "80" indicates its surge current capacity rating of 80 kA per phase (160 kA total device surge capacity).
How does the HEPD80 compare to the HEPD50 and HEPD25?
The HEPD80 is the highest-capacity model in the family (80 kA/phase vs. 50 kA/phase on the HEPD50 and 25 kA/phase on the HEPD25). It uses the same exterior case dimensions as the HEPD50, making both units compatible with the HEPD58MKF flush-mounting kit, whereas the smaller HEPD25 requires the HEPD25MKF kit.
Which flush mount kit is required for recessed drywall installations?
The HEPD80 requires flush mount kit catalog number HEPD58MKF (or earlier HEPD80MKF). It is physically too large to fit the HEPD25MKF kit.
What does it mean if one or both green indicator LEDs are off?
Each green LED indicates active suppression on that specific 120V line phase. If the feeding circuit breaker is ON but an LED is unlit, that phase's internal MOVs have sacrificed themselves during an electrical surge event, and the HEPD80 must be replaced.
