Introduction
FN18 Load Break Switch (which interrupts load currents up to 1,250 A) and a small fault-current circuit combined with a fuse base (F) and current limiting fuses (which break largeshort-circuit currents) create a FN18-type Load Break Switch that provides protection againstamajority of fault types in a modern electric network.
