Abstract
A breaker mechanism for an electrical circuit breaker is disclosed, the breaker mechanism including a spring, a latching mechanism and an actuating element, with which a breaker shaft of the electrical circuit breaker is actuated for breaking (OFF position) or making (ON position) the electric current. In an embodiment, the actuating element is actuated in the direction of the ON position when making the electric current, and the spring is thereby tensioned. Further, the latching mechanism releases the energy of the spring for actuating the breaker shaft of the electrical circuit breaker when the ON position is reached.
Claims17
A breaker mechanism for an electrical circuit breaker, the breaker mechanism comprising:
- a spring;
- a latching mechanism;
- and
- an actuating element, configured to actuate a breaker shaft of the electrical circuit breaker for breaking, in an OFF position, or making, in an ON position, contact for electric current, the actuating element being configured to be actuated in a direction of the ON position when making contact for the electric current, and thereby tension the spring, and the latching mechanism being configured to release energy of the spring to actuate the breaker shaft of the electrical circuit breaker when the ON position is reached by the actuating element, wherein the latching mechanism is configured to be activated by coming into direct mechanical contact with the actuating element, wherein the spring is tensioned to its maximum amount and the latching mechanism is configured to release the energy of the spring to actuate the breaker shaft of the electrical circuit breaker only when the ON position is reached by the actuating element.
A breaker mechanism for an electrical circuit breaker, the breaker mechanism comprising:
- a spring;
- a latching mechanism;
- and
- an actuating element, configured to actuate a breaker shaft of the electrical circuit breaker for breaking, in an OFF position, or making, in an ON position, contact for electric current, the actuating element being configured to be actuated in a direction of the ON position when making contact for the electric current, and thereby tension the spring, and the latching mechanism being configured to release energy of the spring to actuate the breaker shaft of the electrical circuit breaker when the ON position is reached by the actuating element, wherein the actuating element is configured to travel a path from an OFF position to the ON position to reach its switching point and the actuating element travels the entire path when tensioning the spring to the switching point.
