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.

Indicator device of a circuit breaker

A power switch disposed in a housing includes a contact breaker configured to connect and disconnect a low-voltage switchgear from a power source supplying the low-voltage switchgear, a triggering device configured to disconnect the low-voltage switchgear in an overload event, a current detection device, a control device, a first evaluation device configured to evaluate an accidental arc overcurrent, and a second evaluation device configured to evaluate the accidental arc overcurrent. The power switch is configured to be activated via an overcurrent signal generated by an arc monitoring system in response to the accidental arc overcurrent. The overcurrent signal is linked to the at least one triggering signal. The second evaluation has a threshold above a threshold of the first evaluation device. The triggering device is configured to be activated via a turn-off pulse when a signal from the current detection device is above the threshold of the second evaluation device.
