Abstract
A fuse having a composite casing. It includes a radially inner tubular portion that is circular in cross-section, of uniform wall thickness, and houses the fusible element means and a body of pulverulent arc-quenching filler. The casing structure further includes a plurality of angularly displaced rods of an electric insulating material having substantially the same length as the tubular portion of uniform wall thickness of the casing arranged parallel to the axis of said tubular portion, in abutting relation to the outer surface thereof, and adhesively affixed to said outer surface. A pair of spaced external terminal plates closes the tubular portion of the casing and is provided with fasteners having shanks projecting into the end surfaces of said plurality of rods.
