The present disclosure relates to a contact point monitoring module for a vacuum circuit breaker and a vacuum circuit breaker comprising the same. The present disclosure provides a vacuum circuit breaker comprising a push rod assembly which is coupled to a movable electrode of a vacuum interrupter and moves the movable electrode up or down to make a movable contact in a contact closed state or a contact open state, wherein the vacuum circuit breaker comprises a linear sensor which is coupled to a lower side of the push rod assembly and senses displacement according to a moving direction of the push rod; and a sensor holder which is installed adjacent to the lower side of the push rod assembly and is coupled to the linear sensor to process a signal transferred from the linear sensor.
A contact monitoring module for a vacuum circuit breaker, capable of monitoring a wear amount of a contact inside a vacuum interrupter, wherein the vacuum circuit breaker includes a push rod assembly coupled to a movable electrode of a vacuum interrupter to raise up or lower down the movable electrode to bring the movable electrode into a contact closed or inserted state or a contact open or withdrawn state, the contact monitoring module comprising:
A vacuum circuit breaker comprising:
