Claims

[Scope of utility model registration request]

an operating handle protruding outward from the breaker housing; a push plate for opening and closing the movable contact; and a link having one end removably engaged with the push plate and the other end connected to the operating handle. , an equipment protection circuit and disconnector having a lever that receives a component of the force generated at the engagement portion of the link and the push plate and transmits the force to the automatic tripping device and maintains the engagement, An alarm switch fitted into the surplus space of the breaker housing, a retainer that engages with the actuator of the alarm switch, and a retainer that is actuated by the lever and engages with the retainer to prevent movement of the retainer. When the AL latch is actuated by the lever and detached from the retainer during tripping, the actuator of the alarm switch moves the retainer and the alarm switch is activated. Circuit breakers for equipment protection.
