Description
121060R3
121060R3 is a 40-ampere SM-4 power fuse refill unit manufactured by S&C Electric for outdoor distribution substations and panel applications. This fuse is rated for 7.2 kV nominal voltage and provides fast, positive fault interruption through high-speed arc elongation in a solid-material-lined bore. The SM-4 design utilizes an auxiliary arcing rod and spring-cable assembly to achieve reliable overcurrent protection with efficient deionizing action. The fuse element melts under overcurrent conditions, severing the strain wire and initiating the arcing process for rapid fault clearing.
