Why Choose the Mersen NH0GG50V250 NH Fuse-Link?
The Mersen NH0GG50V250 is a high-performance NH size 0 gG fuse-link designed to provide full-range protection against overload and short-circuit currents in industrial electrical installations. Rated at 250 A and 500 V AC, it is suitable for protecting cables, conductors, switchgear and power distribution equipment in demanding commercial and industrial environments.
Its gG utilisation category provides comprehensive protection throughout the fuse-link's operating range. The NH0GG50V250 responds to sustained overloads as well as severe short-circuit faults, while its current-limiting action helps reduce the thermal and mechanical stresses imposed on downstream equipment.
The fuse-link features a robust ceramic body, brass plain-blade terminals, live gripping lugs and a convenient double indication system. Its standard NH0 construction enables installation in compatible NH fuse bases, fuse disconnectors and switch-fuse assemblies used throughout industrial power distribution systems.

Reliable Full-Range Circuit Protection
The Mersen NH0GG50V250 protects electrical installations by interrupting both prolonged overload currents and high-level short-circuit faults. Its full-range gG characteristic makes it suitable for the general protection of cables, conductors and industrial electrical equipment.
During a severe fault, the fuse-link limits the peak current and energy passed to downstream components. This helps minimise damage to busbars, cables, switchgear and connected machinery while supporting reliable operation within correctly designed electrical systems.
Typical Applications
- Industrial power distribution boards.
- Main switchboards and electrical panels.
- Cable and conductor protection.
- Industrial machinery and production equipment.
- Fuse-disconnector and switch-fuse assemblies.
- Commercial and industrial low-voltage installations.
