Abstract

An indicator device displays a status of switching contacts of a circuit breaker that includes an energy store. The indicator device includes a lever and a coupling element. The lever includes a display element and is movable between a triggered position and a non-triggered position based upon at least one operational parameter. The coupling element is operatively connected to the lever so as to be movable between a triggered, position and a non-triggered position by the lever. The coupling element is configured to be further operatively connected to a first actuator of the energy store so as to be movable by the first actuator into the non-triggered position when energy is stored in the first energy store and so as to not be moved from the non-triggered position into the triggered position when energy stored in the energy store is released.
