The AFR series arc protection relay detects electrical arcs in medium and low-voltage equipment, isolating power to minimize the risk of electrical fires. It works to prevent arcing faults in busbars, metal-clad switchgear, and cable boxes.
All Arc flash relays can connect with remote light sensors to detect arc flashes quickly and send a trip signal to interrupt power. They can be used for stand-alone devices or embedded in complex switchgear layouts. Our arc flash relays are trusted for workplace safety by B2B buyers worldwide. ARM arc protection relay, AFR-S arc fault protection relay, and ARF-3 arc flash detection relay are available here.
