AQ-110F arc fiber sensor device with overcurrent is a sophisticated microprocessor-based arc flash protection device with combined current and arc sensing, which provides two (2) integrated trip criteria. It is designed to minimize the damage caused by an arcing fault (arc flash) by tripping the circuit breaker that sources the fault current. Additionally, the complete system self-supervision function of AQ-110F provides the highest level of dependability by continuously monitoring all internal system functions as well as external connections.
The AQ-110F arc fiber sensor device with overcurrent is a multipurpose arc flash protection device which is applicable to a variety of applications. AQ-110F can therefore function as a stand-alone device or as the main unit of a more complex arc protection system via a binary bus.
A wide range for the power supply (18…72 V DC or 92…265 V AC/DC).
