FITTING FOR A CIRCUIT-INTERRUPTING DEVICE ABSTRACT: An end fitting for a high-voltage fuse is disclosed. A conductive end ferrule of the fuse has an enlargement formed near one end thereof, the enlargement having a shoulder remote from the fuse end which defines an exhaust port. The end fitting has a pair of arms with slots for selectively engaging or disengaging a fuse mounting and an externally threaded collar between the arms. The collar has an aperture with a shoulder on the wall thereof which engages the shoulder on the fuse so that the fuse end protrudes from the collar. The collar mates with an exhaust control device having a threaded bore therethrough. The bore contains a lip designed to engage the fuse end. When the fuse is inserted through the aperture in the collar so that the shoulders engage each other, the exhaust control device may be screwed onto the collar to trap the enlarge- ment shoulder and the fuse end between the collar shoulder and the lip thereby mounting the arms to the fuse and closing the exhaust port with the exhaust control device.
