Abstract
Cooling rings of resilient thermally conductive material are installed over a current limiting fuse prior to insertion in a canister housing. The cooling rings provide a heat conduction path from the fuse to the canister wall, thereby reducing heat build up within the canister. The cooling rings are provided with recesses to reduce pressure build-up during fuse insertion in a canister.
