3.1 Unit features AQ-110x is a multipurpose arc flash protection unit and can be applied to a variety of applications. It can be used on its own as a stand-alone unit, or it can be a part of a more complex arc protection system through the binary bus.
Instruction manual Version: 2.01 3.2 Dimensions and installation AQ-110x can be either door-mounted or panel-mounted in a standard 19 inch rack. The unit's dimensions (without cards) are as follows: • Height: 157 mm (6.18 in) • Width: 102 mm (4.02 in) •...
4.4 Current threshold settings The AQ-110x units have four (4) current measurement inputs: three (3) measure phase currents and one (1) measures the residual current. Both the phase and residual current measurements are used as secondary trip criteria in an arc protection system to avoid trips caused by natural light sources.
AQ-SAS™ booklet (can be found at arcteq.fi/downloads/). Please note that there are four booklets: two are for schemes based on IEC standards (MV and LV versions) and the other two for schemes based on ANSI standards (MV and LV versions).
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" page at the end of this manual.
8.2 Inputs 8.2.1 Current measurement inputs Both AQ-110x variants have four (4) CT inputs for measuring the three phase currents and the residual current. Both the phase current and the residual current inputs can be configured to a nominal current of 1 A or 5 A with the DIP switches (for more information, please refer to the "DIP switch settings"...
The binary inputs are activated when a connected DC signal exceeds the specified nominal threshold level of the corresponding input. The nominal threshold level for AQ-110x units is 24 VDC. Please note that the actual activation of the binary input occurs earlier than the specified nominal threshold value (see Chapter 11.5, "Techical Data").
If you want to have more information of these tests, please refer to the routine test reports sent with the AQ-110 unit and/or consult your nearest Arcteq representative for the type test reports.
