AQ-101D Arc flash protection
AQ-101D is a sophisticated microprocessor-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 that sources the fault current. The complete system self-supervision function of AQ-101D provides the highest level of dependability by continuously monitoring all internal system functions as well as external connections.
AQ-101D can be used as a stand-alone unit or as a part of a more complex arc protection system via a binary bus.
