Abstract

This invention discloses a breaker, comprising a housing and a handle. A first accommodating space and a second accommodating space are arranged within the housing; the handle is installed in the first accommodating space and at least partially projects out of the housing; the breaker also comprises a locking device; the locking device comprises a lock head and a sliding member; the lock head is installed on the housing and possesses a cam member; the sliding member is arranged within the second accommodating space in a sliding manner; the sliding member comprises a first side plate, a second side plate, an opening and a first pin; the first side plate is connected to the second side plate; the opening is formed between the first side plate and the second side plate; the cam member extends to the portion between the first side plate and the second side plate through the opening; and the first pin is selectively installed on the first side plate and the second side plate in order to lock the circuit.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a circuit breaker with a locking device. Background technique [0002] As the derivation and supplement of circuit breaker functions, circuit breaker accessories have been increasingly widely used. An example of a circuit breaker accessory is a circuit breaker lockout. When the circuit on the load side of the circuit breaker needs maintenance or is not allowed to be energized, the circuit breaker locking device can be used to lock the circuit breaker in the OFF position to prevent others from closing the circuit breaker by mistake, thereby ensuring the safety of maintenance personnel or users. Reliable use of electrical equipment. However, the structure of the existing circuit breaker locking device is relatively complicated, and there are high precision requirements for installation and fixation, which is not convenient for installation. Contents of the invention [0003] The technical ...
