Comet BK-A

Voltage detector with self-test

Product Features

  • Designed according to IEC 61243-1 (VDE 0682-411), Category S
  • Indoor or outdoor type
  • Visual or visual/audible voltage indication
  • Short device
  • Built-in self-test function

The BK-A is a capacitive voltage detector for testing the voltage on one pole. It is intended for the  detection of operating voltages clearly indicating either the “Voltage Present” or “No Voltage Present” state.
The voltage detector is provided with a built-in self-test funktion which checks the function of the circuit including the contact electrode (comprehensive self-test
function) before each use.
For transportation purposes, the insulating element can be removed from the display with the contact electrode.
According to the German accident prevention standard DGUV Regulation 3  
(Table 1c), the device is subject to maintenance tests with minimum intervals of at least 6 years.
