Technical FAQs 4

What arc flash mitigation solutions are available?

Improve safety with our extensive portfolio of arc flash mitigation solutions including arc quenching and arc-resistant switchgear, Power Xpert XGIS switchgear, Power Xpert Dashboard, Power Defense molded case circuit breaker, Insulgard, arc flash relays and more.

How do arc flash relays work?

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.

What is AFR arc protection relay?

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.

What is arc quenching Magnum DS switchgear?

The arc quenching Magnum DS switchgear detects and extinguishes an arc flash in less than 4 ms to dramatically reduce incident energy. It reacts 10x faster than systems that rely solely on circuit breakers to clear an arc fault, including maintenance switches, ZSI, bus differential relaying and arc detection relays.
