Arc Quenching Switchgear reduces incident energy to a level where the switchgear will survive an arc flash event, while providing enhanced safety and minimal equipment downtime. Arc Quenching Switchgear meets and exceeds testing requirements of C37.20.7 by demonstrating acceptance even when breakers are removed, doors are open and covers are removed, and without the need for ducts, plenums or special enclosure construction.

Arc Quenching Switchgear meets and exceeds ANSI/IEEE C37.20.7 Type 2B testing requirements with breakers removed and breaker, secondary or cable compartment doors open, delivering the highest level of arc-resistant protection without the need for ducts, plenums, special enclosure construction or venting into the room.
Arc Quenching Switchgear employs the Eaton Arc Flash Relay which utilizes advanced algorithms to prevent nuisance operation of the Arc Quenching Device (AQD). Should an arc flash incident occur, restoring service is accomplished by returning the switchgear to normal operating condition and replacing the draw-out AQD which can then reduce downtime from weeks or months to hours.
