SP50 Whole House Surge Protector, Type 1 SPD 50kA, UL 1449 Listed, 120/240V Split Phase, 200kA SCCR, NEMA 4X Weatherproof Surge Protective Device for Main Electrical Panels, HVAC & Home Appliances

PRODUCT DESCRIPTION Protect Your Entire Home with Professional-Grade Surge Protection The SP50 Whole House Surge Protector is a UL 1449 Listed Type 1 Surge Protective Device (SPD) designed to help protect residential electrical systems against damaging transient voltage surges. Whether caused by lightning activity, utility switching events, or large motor loads, electrical surges can shorten equipment lifespan and lead to costly repairs or replacements. Installed at the main electrical panel, the SP50 provides a powerful first layer of protection by helping suppress surge energy before it reaches connected equipment throughout your home. WHY WHOLE HOUSE SURGE PROTECTION MATTERS Electrical surges can originate from lightning strikes, utility grid switching, power restoration events, and even large appliances operating inside the home. These voltage spikes may damage sensitive electronics, HVAC equipment, appliances, and connected systems. A whole house surge protector installed at the service entrance helps reduce the impact of these surges before they spread through your electrical system. HIGH PERFORMANCE PROTECTION The SP50 combines a 50kA maximum surge current capacity per phase with a robust 200kA Short Circuit Current Rating (SCCR), delivering dependable protection in demanding electrical environments. Key Performance Ratings: Maximum Surge Current (Imax): 50kA Nominal Discharge Current (In): 10kA SCCR: 200kA MCOV: 150V / 320V Voltage Protection Rating: * 800V Line-to-Ground (L-G) * 1200V Line-to-Line (L-L) RUGGED NEMA 4X ENCLOSURE Designed for both indoor and outdoor installations, the NEMA 4X weatherproof enclosure helps protect the device against moisture, dust, corrosion, and harsh environmental conditions. The integrated LED status indicator allows quick visual verification that surge protection remains active.
