Abstract

A pawl lever (29) is rotatably mounted in the circuit breaker and has a catch which cooperates with a contact lever during switch-off, to form a latching point. A control device is provided on a slider for controlling the pawl lever so that during switch-on, the pawl lever is released from the control device so that the catch releases the contact lever, tripping the latching point.
