FIELD: electricity.
SUBSTANCE: invention relates to a circuit breaker in a moulded case in which a blocking element is formed on the inside of the lever and an anti-rotating element is formed on its upper side. The blocking element can be brought into contact with the anti-rotating element if the handle rotates to the off position even in the fused state between the fixed contactor and the shifting contactor, thereby preventing the handle from turning to the off position.
EFFECT: possibility to define the condition of the circuit breaker in the moulded case.
