  • Page 10 Figure. 4 - 1. Arc protection device AQ-110P. The AQ-110P is designed according to the latest protection relay standards and is therefore suitable for installations in rough environments. These include utilities and power plants (both traditional and renewable), various heavy industry applications (off-shore, marine, oil, gas, mining, steel, etc.) as well as commercial and institutional electrical systems.
  • Page 11 5 Device features AQ-110P is an arc flash protection device which can be applied to a variety of applications. The device can be used on its own as a stand-alone device, or as a part of a more complex arc protection system by using binary inputs and outputs to connect multiple AQ 100 series devices together.
  • Page 12 Version: 2.05 6 Connections The figure below depicts the connections of AQ-110P. Please note that the SF relay is in the de- energized position; also note that the device has been halved for the image to allow for space for all connector descriptions.

  • Page 20 If necessary, the ends of an AQ-07 cable can be ordered with heat shrinking tubing to avoid light detection outside the protected zone. The covered area can be one (1) or two (2) meters by default; if other lengths are required, please consult the Arcteq sales team. You can find the Contact and reference information chapter at the end of this manual.
