ABSTRACT:
Capacitor fuses differ from fuses intended for other purposes by the nature of their terminal elements. Their terminal elements must be adapted to be gripped by wrenches and hence be hexagonal in cross-section. Disclosed is a capacitor fuse having hexagonal elements press-fitted upon the ferrules of a fuse, the length of ferrule-receiving cavities in said hexagonal elements being substantially equal to the length of the ferrules of the fuse. One of the hexagonal elements is provided with an internally screw-threaded bore and the other of said hexagonal elements is provided with an externally screw-threaded projection extending in a direction away from said casing of the fuse.
