AQ-110F Arc fiber sensor unit with overcurrent
AQ-110F is a sophisticated microprocessor-based arc flash protection unit 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. 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.
AQ-110F is a multipurpose arc flash protection unit and can be applied for a variety of applications. AQ-110F can be used as a stand-alone unit or as a main unit of a more complex arc protection system via a binary bus.
