Problems solved by technology

[0003] The leakage circuit breaker needs to be equipped with an opening and closing indicating mechanism. The traditional leakage circuit breaker uses the action of the moving contact to drive a ejector rod, so that the top of the ejector rod protrudes from the upper surface of the upper cover, which represents a kind of State, when its top no longer protrudes from the upper cover, it represents a state, but this indication method is not clear and unintuitive for non-professionals, so there are disadvantages that lead to misoperation

Abstract

The invention discloses a molded case circuit breaker comprising an on and off indicating mechanism. The molded case circuit breaker comprises a pedestal and an upper cover, wherein a moving contact is arranged in the pedestal; and the on and off indicating mechanism is arranged on the upper cover. The molded case circuit breaker is characterized in that: the on and off indicating mechanism comprises an indicating hole, an on and off indication sliding board, a limited post, a boosting member, a return spring and a driving rod, wherein the indicating hole is formed in the upper cover; the on and off indication sliding board is arranged on the inner wall of the upper cover; the limited post is used for limiting the sliding direction of the sliding board; the boosting member is used for pushing the indication sliding board to slide; the return spring is used for supplying a return elastic force to the indication sliding board; and the driving rod is used for pushing the boosting member to drive the indication sliding board to slide along with the movement of the moving contact. The molded case circuit breaker has the advantage of indicating the current state for a user clearly and intuitively.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker structure design, and in particular relates to a molded case circuit breaker with an opening and closing indicating mechanism. Background technique [0002] Leakage circuit breaker is a circuit breaker that can automatically disconnect the circuit when the residual current reaches or exceeds the specified value under specified conditions, and is used to prevent personal injury, equipment damage, fire and other accidents caused by electric shock and leakage. [0003] The leakage circuit breaker needs to be equipped with an opening and closing indicating mechanism. The traditional leakage circuit breaker uses the action of the moving contact to drive a ejector rod, so that the top of the ejector rod protrudes from the upper surface of the upper cover, which represents a kind of State, when the top end no longer protrudes from the upper cover, it represents a state again, but this indication ...
