Abstract:
A miniature circuit breaker, relating to the field of low-voltage electrical appliances. The miniature circuit breaker comprises a button mechanism (1), a circuit breaker shell (2), and an anti-closing mechanism; the button mechanism (1) is provided at one end of the circuit breaker shell (2) and slidably fits the circuit breaker shell; the anti-closing mechanism comprises a first locking member (3); the first locking member (3) is pivotally provided on the circuit breaker shell (2); one end of the first locking member (3) is in locking fit with the button mechanism (1) to stop the button mechanism (1) from moving towards a closing direction; after the miniature circuit breaker is assembled to a circuit breaker assembly position and mounted in place, the shell at the circuit breaker assembly position acts on the first locking member (3), so that after the first locking member (3) is released from the locking fit with the button mechanism (1), the button mechanism (1) can move towards the closing direction to perform a closing operation. The anti-closing mechanism of the miniature circuit breaker ensures that the circuit breaker can be closed only after being assembled to the circuit breaker position and mounted in place, and ensures the use safety.
