Why Choose the Mersen NH3GG40V315-1 NH Fuse Link?
The Mersen NH3GG40V315-1 is a high-performance NH3 gG fuse link designed to protect low-voltage cables, conductors and industrial electrical equipment against overloads and short circuits. Manufactured to the DIN NH format, it provides dependable full-range circuit protection for demanding power-distribution installations.
This industrial fuse link combines a durable ceramic body with blade contacts, isolated gripping lugs and a double indication system. The isolated tags support safer handling with an appropriate NH fuse replacement device, while the indicators allow maintenance personnel to identify an operated fuse quickly.
With a rated current of 315 A and a rated operating voltage of 400 V AC, the NH3GG40V315-1 is suitable for high-current distribution boards, industrial switchgear and machinery power circuits. Its 100 kA AC breaking capacity enables it to interrupt substantial prospective fault currents safely.
Key Advantages
- Industrial NH3 gG fuse link for full-range cable and line protection.
- 315 A rated current for high-current electrical installations.
- 400 V AC voltage rating suitable for low-voltage distribution systems.
- High 100 kA AC breaking capacity for dependable fault interruption.

Reliable High-Current Circuit Protection
The Mersen NH3GG40V315-1 uses a gG operating characteristic to provide full-range protection against overload currents and short circuits. When current exceeds safe operating levels, the internal fuse element interrupts the circuit before excessive heat or electrodynamic forces can cause serious damage to cables and connected equipment.
Its NH3 blade-contact construction is designed for use with a compatible NH fuse base or fused switch-disconnector. The ceramic body offers excellent thermal and electrical insulation, making the fuse suitable for demanding industrial installations with high continuous currents and substantial prospective short-circuit levels.
Typical Applications
- Industrial low-voltage distribution boards.
- High-current electrical switchgear.
- Cable and conductor protection.
- Industrial machinery power circuits.
- Commercial and manufacturing facilities.
- Motor control centres and electrical panels.
- NH fuse bases and fused switch-disconnectors.
