Why Choose the Mersen NH2GG69V250-1 NH Fuse Link?
The Mersen NH2GG69V250-1 is a high-performance DIN NH gG low-voltage fuse link designed to provide reliable protection for cables, electrical equipment and industrial power distribution systems. Manufactured by Mersen, this full-range fuse link protects electrical installations against sustained overloads and severe short-circuit currents.
Featuring a 250 A rated current, a 690 V AC rated voltage and an NH2-size body, the NH2GG69V250-1 is suitable for demanding industrial distribution circuits. Its gG operating characteristic enables it to interrupt overcurrents across the complete protection range, from the lowest fusing current up to its rated breaking capacity.
The fuse incorporates a double blown-fuse indicator for rapid fault identification and isolated gripping lugs for safer handling by qualified electrical professionals. Its robust ceramic body, silver-plated copper blade contacts and standard DIN NH construction support dependable operation in switchboards, fuse-switch disconnectors and industrial control systems.

Reliable Protection for Industrial Power Systems
The gG utilisation category provides full-range protection against overload and short-circuit currents. This makes the Mersen NH2GG69V250-1 suitable for protecting distribution cables, feeders, switchgear and general-purpose industrial electrical equipment without requiring a separate short-circuit fuse.
Its current-limiting performance helps reduce the thermal and electrodynamic stresses caused by high fault currents. This can minimise damage to connected equipment, improve electrical safety and reduce downtime following an overcurrent or short-circuit event.
Typical Applications
- Industrial power distribution systems.
- Electrical switchboards and distribution panels.
- High-current cable and feeder protection.
- NH fuse-switch disconnectors.
- Industrial machinery and control systems.
- Commercial and infrastructure electrical installations.
