Arc flash circuit breaker

Masterpact Low Arc Flash circuit breakers are designed and tuned to provide balanced protection for both overcurrent and arc flash. The breakers incorporate a blow-open design that clears faults quickly and provides arc flash protection at the lower current levels often associated with arc flash incidents. The design allows the circuit breaker to go into an accelerated opening mode at about 30kA, while continuing to accelerate opening times through the interrupting rating of 200kA at 508VAC. Even below that level, the circuit breaker will open instantaneously with a rapid opening time at current values down to its instantaneous setting. It also houses a filtered arc chute that contains an assembly of metallic grids and meshes that reduce the gases released during an interruption.
