摘要： Disclosed herein is a circuit breaker having a closing resistor, which is capable of preventing impact caused when the circuit breaker is opened and closed from being transferred to peripheral structures. The circuit breaker having a closing resistor includes a fixed part having a fixed contact, a movable part having a movable contact, a closing resistor unit connected to the fixed part and having a closing resistor unit contact, a closing resistor movable part connected to the movable part and having a closing resistor movable contact, and a support structure slidably coupled to the closing resistor unit in a direction parallel to a movement direction of the closing resistor movable part, thereby enabling impact and vibration applied to the closing resistor unit to be absorbed by the support structure.
