Why Choose the Mersen NH1GG69V125 NH Fuse-Link?
The Mersen NH1GG69V125 is a premium NH size 1 gG fuse-link designed to provide full-range protection against overloads and short circuits in industrial electrical systems. Rated at 125 A and 690 V AC, it is ideal for safeguarding cables, switchgear, control panels and power distribution equipment in demanding industrial applications.
Manufactured with a gG utilisation category, the NH1GG69V125 delivers comprehensive protection across its entire operating range, making it suitable for general-purpose circuit protection without requiring additional fuse protection. Its high current-limiting capability helps minimise thermal and mechanical stress during fault conditions, reducing damage to connected equipment.
The fuse-link incorporates a robust ceramic body, silver-plated copper blade contacts, live gripping lugs and a double indication system for rapid fuse status identification. Manufactured to DIN NH standards, it fits compatible NH1 fuse bases and switch-fuse assemblies used throughout industrial power distribution systems.
