Abstract

Disclosed is a movable contactor assembly of a circuit breaker capable of enhancing a current limiting function by maintaining a contact state between a movable contactor and fixed contactors in a closed circuit state, by preventing the separated movable contactor from returning towards the fixed contactors at the time of a current limiting operation, by accelerating a separation operation of the movable contactor from the fixed contactors at the time of a current limiting operation, and by continuously maintaining a separated state of the movable contactor from the fixed contactors until a trip operation is performed by a trip mechanism.

Description

technical field [0001] The present invention relates to a movable contactor assembly for a circuit breaker, and more particularly, to a movable contactor assembly for a circuit breaker by improving the movable contactor and support The assembly of the rotating shaft of the movable contactor can enhance the current limiting performance. Background technique [0002] Typically, circuit breakers are installed at power supply distribution panels between several power supply systems of factories and buildings. A circuit breaker is used as a switch to supply or cut off the power supply to the load side in the no-load state, and to cut off the power supply from the power supply side to the load side in the load state when a strong abnormal current flows through the circuit due to a short circuit or a ground fault power supply to protect circuits and components on the load side. [0003] 1 is a cross-sectional view showing an internal configuration of a circuit breaker according t...
