NH fuse-links gg 69VAC NH fuse-links gg 69VAC LOW VOLTAGE IEC FUSES IEC NH FUSE-LINKS FEATURES & BENEFITS Dimensions in accordance with DIN 43 62 Live tags Top indicator Lead free contact blades % cadmium APPLICATIONS gg: General purpose (protection of cables and LV-networks) 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. Type gg NH fuse-links are full range breaking capacity fuse-links and are used to protect cables and equipment. They can interrupt any current surge, from the lowest fusing current up to their breaking capacity, and so can be used alone as protection. They also protect electrical devices and industrial set-ups from the electrodynamic effects of very high short-circuit currents.
