Abstract
A method is disclosed for operating a circuit breaker. The circuit breaker includes an operating lever, a latching mechanism and an electrical contact system with a movable contact and a fixed contact. The operating lever is movable into an ON-position and an OFF-position. Further, the operating lever is mechanically connected to the electrical contact system via the latching mechanism such that when the operating lever is in its OFF-position, the contacts of the electrical contact system are opened and when the operating lever is in its ON-position, the contacts of the electrical contact system are closed. Further, such a circuit breaker is also disclosed.

A method for operating a circuit breaker, the circuit breaker including an operating lever, a latching mechanism and an electrical contact system with a movable contact and a fixed contact, the operating lever being movable into an ON-position and an OFF-position and being mechanically connected via the latching mechanism to the electrical contact system such that when the operating lever is in the OFF-position, the movable and fixed contacts of the electrical contact system are opened and when the operating lever is in the ON-position, the movable and fixed contacts of the electrical contact system are closed, the method comprising:
- moving the operating lever in the OFF-position;
- and
- preparing a subsequent activation of the latching mechanism during movement of the operating lever in the OFF-position by resetting the latching mechanism.
A circuit breaker, comprising:
- an operating lever;
- a latching mechanism;
- and
- an electrical contact system including a movable contact and a fixed contact, the operating lever being movable into an ON-position, an OFF-position and a RESET-Position and being mechanically connected via the latching mechanism to the electrical contact system such that when the operating lever is in the OFF-position, the movable and fixed contacts of the electrical contact system are opened, and when the operating lever is in the ON-position, the movable and fixed contacts of the electrical contact system are closed, wherein when moving the operating lever in the RESET-position, an activation of the latching mechanism is prepared by resetting the latching mechanism, and wherein the OFF-position of the operating lever and the RESET-position of the operating lever are identical.
