Z214014 FER

The NH system is classified among plug-in fuse systems and is composed of fuse-base, (possibly including terminal covers and phase barriers), fuse link with blade contact fuse link replacement device (LV HRC fuse puller) since the design of this system cannot guarantee non-interchangeability of rated current, it must be handled by a qualified professional. NH fuse links are used for the protection of transformers. The time/current characteristic is especially adapted to that of the protected transformer and implies optimal selectivity to NH fuse links characteristic gG. The fuses can be loaded with 3 times nominal current for up to 10 hours. The fuse link operates at 5 times nominal transformer current within 2 hr.
