Protect your electronics from damage with this Square D Brand Home Electronics Protective Device (HEPD). This affordable and compact surge suppressor is compatible with all brands of residential load centers. It works together with surge protection plug strips to suppress power surges for sensitive electronics.

HEPD80 Residential Surge Protection.

Would Recommend

Best solution for installing residential surge protection when breaker slots are all occupied. Easy install but should have knowledge of electric system to undertake this project. One of the highest commercially available capacity related devices for 240/120 volt panel. Squard D is a long respected name in service equipment.
