AQ-103 Arc Flash Protection - Medium Voltage
AQ-103 sophisticated microprocessor-based arc flash protection unit for arc light detection.
The AQ-103 acts as a sub-unit to AQ-110P (or, AQ-110F) in an AQ-100 arc protection system. It can also function as a stand-alone unit in light-only systems. The AQ-103 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-101 provides the highest level of dependability by continuously monitoring all internal system functions as well as with external connections. AQ-103 provides communication through RS-485 and Modbus protocol as ordering options. Through the Modbus communication AQ-103 connects to a local display (AQ-S254) for indication of exact fault location and to a SCADA system either trough a AQ-S254 or RTU.
