Reliable Protection for Industrial Electrical Circuits
The Mersen NH0GG69V63-1 uses a full-range gG fuse characteristic to protect cables, conductors and general-purpose electrical equipment. When excessive current passes through the fuse element, it safely interrupts the circuit before damaging thermal and electrodynamic stresses can affect downstream components.
Its 690 V AC rating and high breaking capacity make it suitable for demanding industrial installations with substantial prospective fault currents. The fuse link is designed for compatible NH fuse bases and switch-fuse equipment and must be installed or replaced by qualified electrical personnel using suitable NH fuse-handling equipment.
