Claims

[Scope of utility model registration request]

An opening/closing lever whose one end engages with a contact support that supports the movable side of the main contact and which is connected via a toggle link to an operating handle that controls contact and separation from the fixed side, and the engagement of the other end of the opening/closing lever. A latch that has a mating ridge and is swingably supported, the claw is extended and is spring-biased toward the return position, and a latch that engages with the claw of the latch, is swingably supported, and has a latch that is spring-biased toward the return position. A tripping crossbar made of synthetic resin that can engage with a tripping device such as an overcurrent or an overcurrent, and a helical twisting crossbar that engages and biases the tripping crossbar to maintain the closed state of the main contact. an opening/closing operation mechanism comprising a return spring and at least a U-shaped side plate that supports the tripping crossbar and engages with the tripping crossbar return spring; The legs of the side plate are bent inwardly and inserted between the legs of the tripping crossbar, thereby engaging the side plate and the tripping crossbar, and the return spring is moved to the side. An opening/closing operation mechanism for an earth leakage breaker, characterized in that the plate is tripped from the outside and engaged with a crossbar.
