Description

The AQ-101DLV arc flash protection device is a sophisticated microprocessor-based arc flash protection unit 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-101DLV provides the highest level of dependability by continuously monitoring all internal system functions as well as with external connections.

The AQ-101DLV arc flash protection device acts as a sub-unit to AQ-110P (or, AQ-110PLV) in an AQ 100 arc protection system. It can also function as a stand-alone unit in light-only systems.

Highlights:
  • Easy DIN rail installation.
  • A wide range for the power supply (18…72 V DC or 92…265 V AC/DC).
  • Max. 12 arc light point sensors (3 point sensors per channel) and 1 fiber loop sensor (optional) per device.
  • 4 trip relays (with 7 ms total trip time).
  • Complete system self-supervision.
  • 2 binary inputs and 1 binary output.
  • A multifunction push button (“SET”) with auto-configuration, indication reset, and system check.
  • 12 indication LEDs.
