ABSTRACT:
The invention relates to an indicator and/or interrupter circuit for an electrical capacitor. On the build-up of internal pressure in the capacitor a switch is caused to operate to open a set of contacts which thereby energizes an indicating lamp to provide a visual indication of a failed or over-pressure condition in the capacitor. The opening of the switch may also cause an interruption of current flow through a holding coil and this current interruption causes a circuit interrupter to operate mechanically and thereby remove the capacitor from its circuit.
