Device for display of tripping of circuit breaker due to short circuit current

摘要

The circuit breaker has an auxiliary switch attached to the side of the switchgear and accommodating a contact carrier (12). A retainer holds the contact carrier in its rest or start position. The retainer is a lever (25) that is pivotably mounted at one end. In the rest position, a stage on the contact carrier lies against the lever. The lever is pivoted by a transfer member (10) so that the retainer is released from the ledge, and the contact carrier is brought into an indication position.
