Comet BK-I | Comet BK-A

The Comet BK-I / BK-A devices are single-pole capacitive voltage detectors in short version. They are intended for the detection of operating voltages clearly indicating either the “voltage present” or “voltage not present state. The voltage detectors are provided with a built-in self-test facility 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.
