AQ-110P Arc point sensor unit with overcurrent

AQ 110 is a sophisticated micro-processor based arc flash protection unit with combined current and arc sensing. Combined current and arc sensing provides an integrated dual trip criteria. 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 110 complete system self-supervision function provides the highest level of dependability by continuously monitoring all internal system functions along with external connections.
