Description
The AQ-110FLV arc fiber sensor device with overcurrent is a sophisticated microprocessor-based arc flash protection unit with combined current and arc sensing, which provide 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 the AQ-110FLV arc fiber sensor device with overcurrent provides the highest level of dependability by continuously monitoring all internal system functions as well as external connections.
Features:
- A wide range for the power supply (18…72 V DC or 92…265 V AC/DC).
- Three-phase current detection.
- A maximum of 3 fiber loop sensors.
- Connectivity to the AQ-2000 and AQ-1000 arc quenching systems.
- 1 high-speed output (HSO).
- 1 high-speed semiconductor trip output (HST).
- 4 trip relays.
- 1 system failure relay.
- 1 fast binary output.
- 2 fast binary inputs.
- 1 multifunction push button.
- Non-volatile memory.
- 18 indication LEDs.
