Why Choose the Mersen NH1GG69V100-1 NH Fuse Link?
The Mersen NH1GG69V100-1 is a high-performance NH1 gG fuse link designed to provide dependable overload and short-circuit protection for low-voltage electrical distribution systems. Manufactured in accordance with recognised DIN NH and IEC requirements, this full-range fuse protects cables, conductors, switchgear and general-purpose electrical equipment in demanding industrial and commercial installations.
With a rated current of 100 A, a maximum operating voltage of 690 V AC and a 400 V DC rating, the NH1GG69V100-1 is suitable for electrical systems requiring reliable protection at elevated operating voltages. Its 80 kA AC breaking capacity allows substantial fault currents to be interrupted safely, helping minimise thermal and electrodynamic stress on connected equipment.
The fuse features a durable ceramic body, silver-plated copper blade contacts and isolated gripping lugs for safer handling with an approved NH fuse replacement device. Its double indicator provides clear confirmation when the fuse has operated, while the standard NH1 format supports straightforward installation in compatible fuse bases and switch-fuse assemblies.
