Why Choose the Mersen Y1054295 NH4a Fuse-Link?
The Mersen Y1054295, catalogue reference NH4AGG50V1600, is a high-capacity DIN NH gG fuse-link designed to protect low-voltage cables, electrical equipment and industrial distribution networks against overloads and short circuits. Its full-range gG operating characteristic enables the fuse-link to interrupt fault currents from low overcurrent levels through to severe short-circuit conditions.
Engineered for demanding industrial power-distribution applications, the Y1054295 combines a durable ceramic body with silver-plated copper contacts and plain blade terminals. Its live gripping lugs provide compatibility with suitable NH fuse replacement equipment, while the integrated centre indicator allows maintenance personnel to identify an operated fuse-link quickly.
With a rated current of 1600 A, an AC voltage rating of 500 V and a DC voltage rating of 250 V, this NH4a fuse-link is suitable for high-current switchboards, distribution panels and industrial installations. Its 120 kA AC breaking capacity provides dependable interruption of high prospective fault currents.

Reliable Protection for Cables and Electrical Equipment
The Mersen Y1054295 uses a gG full-range characteristic to provide both overload and short-circuit protection. This allows the fuse-link to protect cables, conductors, switchgear and connected equipment across a broad range of fault-current conditions without requiring a separate short-circuit protection device.
Its high breaking capacity helps limit the damaging thermal and electrodynamic effects associated with severe electrical faults. Installation, removal and maintenance should be completed by appropriately qualified personnel using compatible NH fuse bases and approved fuse replacement equipment.
Typical Applications
- High-current low-voltage distribution networks.
- Industrial switchboards and main distribution panels.
- Cable and conductor protection.
- Electrical equipment and machinery protection.
- Commercial and industrial power infrastructure.
- OEM switchgear and power-distribution assemblies.
