AQ-110P Arc point sensor device with overcurrent
The AQ-110P arc point sensor device with overcurrent is a sophisticated microprocessor-based arc flash protection device 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. Additionally, the complete system self-supervision function of AQ-110P provides the highest level of dependability by continuously monitoring all internal system functions as well as external connections.

Description:
The AQ-110P arc point sensor device with overcurrent is a multipurpose arc flash protection unit and is applicable to a variety of applications. AQ-110P can therefore function as a stand-alone device or as the main unit of a more complex arc protection system via a binary bus.
Features:
- A wide range for the power supply (18…72 V DC or 92…265 V AC/DC).
- Three-phase current detection.
- Residual current detection.
- A maximum of 12 point sensors (3 point sensors per channel).
- A maximum of 1 fiber loop sensor (optional).
- Connectivity to both MV (SIQuench) and LV (AQ-1000) arc quenching systems.
- 2 high-speed outputs (HSOs, 2 ms trip time).
- 4 trip relays (with 7 ms trip time).
- 1 system failure relay.
- 1 fast binary output.
- 2 fast binary inputs.
- 1 multifunction push button.
- Non-volatile memory.
- 20 indication LEDs.
