WT gG/gL fuse link NH000 80A 1115282112T

The WTNH fuse link is a deliberately introduced "weak link" into the circuit, which provides the protected object with protection against thermal and electrodynamic effects of short circuits and overloads. Disconnecting sometimes very high power (up to 100 MVA) was achieved by a special design of fuses placed in the extinguishing medium (quartz sand), precise matching of the fuse to divide the electric arc and its cooling by quartz sand.
