Square D HEPD50 Universal Whole House Surge Protector – 50kA, 120/240V, 1-Phase, Black

Overview

The Square D HEPD50 Universal Whole House Surge Protector is a compact, affordable protection device designed for residential load centers. It works alongside surge protection strips to limit surges before they reach connected electronics, and it adds a layer of protection for important home equipment that strips alone may not fully shield.

Key benefits

• Compact, easy-to-install design that fits most residential load centers from different brands
• Green status LED provides a quick, at-a-glance indication that protection is active
• NEMA 4X rated for indoor or outdoor use, suitable for a range of installation environments
• High surge handling with a 50,000 amp rating and 25,000 amp SCCR to help mitigate energy spikes
• CSA and UL 1449 3rd Edition Type 1 SPD certification for safety and performance
• Manufacturer’s 3-year warranty and a 50,000 residential downline warranty for added peace of mind

What it protects

While surge strips provide local outlet protection, the HEPD50 helps reduce surges that could overwhelm those strips. It also supports protection for essential home items that may not be fully covered by strips alone, such as washers, dryers, refrigerators, stoves, and air conditioning units.

Real-world use cases

• Safeguards a busy kitchen by limiting surge energy entering the main panel that feeds a refrigerator and range
• Offers protection for laundry areas where washers and dryers operate, reducing the impact of transient spikes
• Provides versatile protection for spaces that experience outdoor or weather-related surge events

Installation and maintenance

Connects easily to any residential load center, with a clear green LED to confirm protection is active. The device aligns with industry standards and is backed by a solid warranty, helping homeowners feel confident in their protection setup.
