The AQ-110PLV arc point sensor device with overcurrent is a sophisticated microprocessor-based arc flash protection device with combined current and arc sensing, which provide two (2) integrated trip criteria. When an AQ-110PLV arc point sensor device with overcurrent detects an overcurrent in the incoming feeder as well as a light signal from a sub-unit or from a direct light sensor, it minimizes 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-110P provides the highest level of dependability by continuously monitoring all internal system functions as well as external connections.
A wide range for the power supply (18…72 V DC or 92…265 V AC/DC).
