    Why Add Surge Protection?

    Homes today contain an average of over $15,000 worth of unprotected equipment. Surge strips only offer low-level suppressions, leaving them powerless to block appliance-damaging surges. Square D™ Whole Home Surge Protection blocks the shock caused by surges at the load center, so you can rest assured your electronics are protected.

    Whole Home Surge Protective Devices (SPDs)

    HEPD80-IC-490x490

    Often people think of power strips when they hear "surge protection". Commonly used as an extension to outlets, many power strips offer no surge suppression at all. Others offer only low-level surge suppression, leaving them subject to surge damage.

    Everything Electrical is Protected

    Whole Home Surge Protective Devices reduce higher-level surges that might otherwise overwhelm plug strips and damage connected household equipment. SPDs also provide surge suppression for important items that are not compatible with plug strips, such as a home's HVAC, washer, dryer, refrigerator, stove, oven, and lighting. Protect your investments with Square D Whole Home Surge Protective Devices.

    Innovation of Square D Surge Protection

    Better Protection

    With surge capacity up to 80ka, Square D SPDs are prepared to protect your home against even the highest of surges, far beyond the capability of power strips and many other surge protective devices. And, the protection is from the load center, so all appliances and electronics in your home are protected, not just those you can plug into a surge strip.

    Ease of Installation with Plug-on Neutral

    Square D Plug-on Neutral Surge Protective Devices offer the easiest, quickest installation around. With Plug-on Neutral connectivity, the SPD connects directly to the equipment bus of a QO or Homeline Plug-on Neutral load center, delivering superior surge suppression performance with no wiring needed, saving you time and money.
