ABSTRACT:
A fine ozone corrosion resistant fuse wire is supported between conductive terminals which are, in turn, supported on and spaced apart by rigid insulator spacing means so that the fuse wire is extended. Insulator shield means is placed over the fuse wire over a substantial length of the insulator spacing means to shield the insulator spacing means from vaporized filament material to ensure that in all possible fuse failure modes that the circuit is completely broken but including a portion is unshielded so that vaporized material will plate on to the insulator to permit quick detection of a failed fuse. The rigid insulator spacing means may take the form of a rod generally parallel to the fuse with the terminals as end caps fitting over the rod or it may take the form of a tubular member fitting around portions of the terminals and confining the fuse internally, preferably so that oxygen cannot readily reach the fuse when it is used in a concentrated oxygen atmosphere.
