Description
AQ-103 Arc flash protection device is a sophisticated microprocessor-based arc flash protection device for arc light detection. 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-103 provides the highest level of dependability by continuously monitoring all internal system functions as well as with external connections.
The AQ-103 arc flash protection device 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. Additionally, AQ-103 can provide Modbus RTU communication via an RS-485 port. Through Modbus communication, AQ-103 connects to a local display (AQ-S254A) for indication of exact fault location and to a SCADA system either through an AQ-S254 device or a remote terminal unit (RTU).
Highlights:
- A wide range for the power supply (18…72 V DC or 92…265 V AC/DC).
- Max. 14 fiber loop sensors per device (1 sensor/channel).
- 4 trip relays (with 7 ms total trip time).
- Complete system self-supervision.
- 2 binary inputs, 1 binary output, and 1 high-speed output.
- A multifunction push button (“SET”) with auto-configuration, indication reset, and system check.
- 25 indication LEDs.
- Modbus RTU communication (optional).
