Abstract

An oil expulsion fuse having a pair of contacts solidly secured to the ends of a high strength outer insulating tube. A resilient non-conducting inner sleeve is mounted within the bore of the insulating tube and contact assembly, the sleeve and tube being closely fit to each other. A fusible link is assembled in the bore of the resilient sleeve secured to the contact ends by fuse clamps. The fusible link includes a support tube also composed of a resilient non-conductive material which together with the inner sleeve absorb and trap high energy fuse link particles during a fusing operation.
