AQ-103LV is a sophisticated microprocessor-based arc flash protection unit for arc light detection. AQ-103LV acts as a sub-unit to AQ-110P (or, AQ-110P) in an AQ-100 arc protection system. It can also function as a stand-alone unit in light-only systems. AQ-103LV 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-101LV provides the highest level of dependability by continuously monitoring all internal system functions as well as with external connections. AQ-103LV provides communication through RS-485 and Modbus protocol as ordering options.
