Abstract
Disclosed is an arcing rod catcher for a high voltage fuse which engages the arcing rod when the arcing rod moves during fuse operation so that the arcing rod will not bounce back or reverse directions during and after fuse operation. Since the arcing rod movement is utilized to actuate a fuse latch assembly to release the fuse from an upper mounting when it operates, it is necessary for the arcing rod to move to the operating position and remain in that position to permanently indicate that the fuse has operated and to prevent the possibility that a blown fuse will be re-latched into a closed position. The disclosed invention utilizes engaging fingers which allow the arcing rod to pass in one direction but prevent the arcing rod from returning in the opposite direction when the fuse operates.
