A coaxial cable fuse having a central conductor, an outer conductor disposed coaxially with respect to the central conductor, an insulating medium disposed between the central conductor and the fusible outer conductor, and an insulating layer covering the fusible outer conductor. The outer conductor may be composed of fusible conductor for causing an open circuit to be formed in the outer conductor in response to an electrical current passing through the outer conductor. The open circuit is formed prior to any substantial heating of the exterior insulating layer of the coaxial cable to which the fuse is attached to reduce the likelihood of fire hazard due to heating of the insulating layer. The coaxial cable fuse may be used in an electrical interface apparatus adapted to interconnect a coaxial distribution cable and a premise coaxial cable. The electrical interface apparatus has a housing and a coaxial cable protector with a surge protector and a fail-short mechanism disposed in the housing. The coaxial cable fuse is preferably connected between the coaxial distribution cable and the coaxial cable protector.
