Why Choose the Mersen NH1GG40V224-1 NH Fuse Link?
The Mersen NH1GG40V224-1 is a high-performance DIN NH gG low-voltage fuse link designed to protect cables, electrical equipment and industrial power distribution systems against overloads and short circuits. Manufactured by Mersen, this full-range fuse link provides dependable fault protection for switchboards, distribution panels and demanding industrial installations.
Featuring a 224 A rated current, a 400 V AC rated voltage and an NH1-size body, the NH1GG40V224-1 is suitable for high-current cable and feeder protection. Its gG operating characteristic enables it to interrupt overcurrents across the complete operating range, from sustained overload conditions to severe short-circuit faults.
The fuse incorporates a double indication system for rapid identification of an operated fuse and isolated gripping lugs for safer handling by qualified professionals. Its ceramic body, silver-plated copper blade contacts and high breaking capacity support reliable operation in industrial electrical systems.

Reliable Protection for Industrial Electrical Systems
The gG utilisation category provides full-range protection against both overload and short-circuit currents. This makes the Mersen NH1GG40V224-1 suitable for protecting cables, distribution feeders, switchgear and general-purpose industrial electrical equipment.
Its current-limiting performance helps reduce the thermal and electrodynamic stresses generated by severe electrical faults. This can minimise damage to connected equipment, improve installation safety and reduce downtime following an overcurrent event.
Typical Applications
- Industrial power distribution systems.
- Electrical switchboards and distribution panels.
- High-current cable and feeder protection.
- Fuse-switch disconnectors.
- Industrial machinery and control systems.
- Commercial and infrastructure electrical installations.
