Product Details

This Class L fuse offers fast-acting, short-circuit protection of circuit breakers with lower interrupting ratings and non-inductive loads such as lighting and heating circuits. It features 99.9% pure silver links for low watt loss and operating temperature on normal current levels. It also features high-grade silica-sand filler to accelerate the response of fuses to short circuits by having a quenching effect upon the fuse arc.
