Trip mechanism for direct current molded case circuit breaker

A trip mechanism for a direct current (DC) molded case circuit breaker, the trip mechanism comprising:

• a trip mechanism part including an instantaneous trip mechanism connected to a circuit, the instantaneous trip mechanism including a movable member to operate according to a fault current instantaneous breaking required which flows on the circuit, and a thermal trip mechanism connected to the circuit, the thermal trip mechanism including a bimetal to operate according to an over current flowing on the circuit, the trip mechanism part being provided for one of two adjacent poles;
• a crossbar that is rotatable by contacting and pressing of the movable member of the instantaneous trip mechanism or the bimetal of the thermal trip mechanism;
• and
• a shooter that is provided to be rotatable by contacting of the crossbar rotating, the shooter provides an output of the trip mechanism,
• wherein the cross bar comprises:
• a first power receiving portion that is provided in corresponding to the bimetal of the thermal trip mechanism, the first power receiving portion formed to protrude upwardly, and the first power receiving portion receiving a pressing force from the bimetal;
• a second power receiving portion that is provided in corresponding to the movable member of the instantaneous trip mechanism, the second power receiving portion formed to protrude upwardly, and the second power receiving portion receiving a pressing force from the movable member of the instantaneous trip mechanism;
• and
• an output protrusion portion that is provided to face the shooter and provided to protrude upwardly from the crossbar, the output protrusion portion providing an output of the crossbar which drives the shooter to rotate.
