Safety interlocking molded case circuit breaker

The invention discloses a safety interlocking molded case circuit breaker, and relates to the technical field of circuit breakers, the safety interlocking molded case circuit breaker comprises a molded case circuit breaker body, and the outer side of the molded case circuit breaker body is provided with a mistaken touch prevention mechanism. When the operating handle jumps to a lower position due to automatic circuit breaking of the circuit breaker or the circuit breaker is manually pulled downwards, the eccentric arm located on the outer side of the special-shaped gear slides downwards along with the locking sliding block until the locking sliding block completely moves downwards into the clamping cushion block, and clamping teeth on the outer side of the locking sliding block enter grooves matched with the clamping cushion block, so that the locking sliding block is locked. At the moment, the position of the locking sliding block is in a limited state, namely, the position of the operation handle is locked,
