AQ-110PLV Arc point sensor unit with overcurrent
AQ-110PLV is a sophisticated microprocessor-based arc flash protection unit with combined current and arc sensing, which provides two (2) integrated trip criteria. When AQ-110PLV 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.
