Abstract
A pin indicating fuse construction incorporates a protective shield member that isolates an indicator assembly from a main-fuse link. By use of the inventive protective shield, arc-quenching filler may be excluded, resulting in a less-costly, more reliable fuse construction. The main fuse link is arranged within the fuse in such a manner so as to minimize potential interference with the actuator assembly during activation of the indicator assembly.
