Industrial fuse-link WT-00C/gG 20A 500 - delayed 004111431

Industrial fuse links are designed to protect electrical installations against the effects of short circuits and overloads. Fuse-links with fast gF characteristics are intended for use in rural power lines - where, due to scattered buildings, small cross-sections of wires, low short-circuit powers of transformers, short-circuit currents may be small, and thus their tripping time by the fuse-link delayed - long. The operation of the gG slow-blow fuse-link at small overloads is slower than that of fast-acting fuse-links, and very fast in the event of a short-circuit. They have a trip indicator and are mounted in fuse bases with an insulating holder. Insulation class C-VDE 0110.
