Abstract
A method is disclosed for operating a circuit breaker, the 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 via the latching mechanism to the contact system 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.
Claims19
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 methods comprising:
- moving the operating lever in the ON-position;
- transferring the movement of the operating lever via the latching mechanism to the contact system by moving a connecting device of the latching mechanism, mechanically directly connected to the contact system in a first direction, and thereby moving the movable contact;
- reaching the ON-position of the operating lever and closing the movable and fixed contacts of the contact system;
- and
- inhibiting a movement of the connecting device in a second direction, different from the first direction.
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 is 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 latching mechanism including a connecting device mechanically directly connected to the contact system, movable in a first direction when the operating lever is moved into the ON-position, wherein movement of the connecting device in a second direction is inhibited when the operating lever is in the ON-position and wherein the second direction is different to the first direction.
