AQ-101D Arc flash protection

AQ 101D is a sophisticated micro-processor based arc flash protection unit for arc light detection. It is designed to minimize the damage caused by an arcing fault (arc flash) by tripping the circuit breaker sourcing the fault current. The AQ 101D complete system self-supervision function provides the highest level of dependability by continuously monitoring all internal system functions along with external connections.
