PURPOSE:To prevent the contactor from being impaired due to impact of a device during its transportation, by mounting a stopper to an upper portion of the vacuum valve, which stopper projects upwardly through a top surface of the frame and abuts on the fuse-side end portion of the conductor. CONSTITUTION:A bolt projecting upwardly through the top surface of a frame 2 is disposed, as a stopper 14, with its hexagonal head being directed upside and is fixed to a fixing nut provided to an upper portion of a vacuum valve 1. A connecting conductor 9 is provided so as to abut on the top end of the stopper 14. Since the stopper 14 serves as an anti-vibration member for the conductor 9, the conductor 9 is free from impairment even when the device receives an impact. Nor is a fuse 4 drawn off. |
