AST-02 arc sensor tester kit


The AQ-AST-02 arc sensor tester allows for the field-testing of AQ-02 point sensors when conducting commissioning tests of a complete arc protection system. The tester helps to confirm that the system is wired and installed correctly by following the system’s signal propagation.


  • Activates either locally (with the injector included in the test kit) or externally with third-party testing equipment.
  • Tests the correct operation of the circuit breaker failure protection function.
  • Is compatible with all AQ 100 series host units in both low-voltage and medium-voltage applications.
