Why Choose the Mersen NH1GG50V355 NH Fuse Link?
The Mersen NH1GG50V355 is a robust NH gG low voltage fuse link designed to provide full-range protection for industrial cables, conductors and electrical distribution equipment. Manufactured as part of the established Mersen NH fuse-link range, it protects circuits against both sustained overloads and high short-circuit currents in demanding low voltage installations.
This DIN-standard fuse link combines a 355 A rated current with operating ratings of 500 V AC and 250 V DC. Its double indicator provides clear visual confirmation when the fuse has operated, helping maintenance personnel identify faults quickly and reduce equipment downtime.
With an NH1 fuse size, durable ceramic construction and live gripping lugs, the NH1GG50V355 is suitable for installation in compatible NH fuse bases within industrial switchboards, distribution panels and motor control systems. Its high breaking capacity supports reliable protection in installations where substantial prospective fault currents may occur.

Reliable Protection for High-Current Electrical Circuits
NH fuse links interrupt excessive current before cables, switchgear and connected equipment suffer serious thermal or mechanical damage. The Mersen NH1GG50V355 uses a gG characteristic to provide full-range protection, covering both overload conditions and high-energy short circuits.
The fuse link is intended for use in a correctly rated NH fuse base and should be installed or replaced by a qualified electrical professional using suitable personal protective equipment and an approved NH fuse puller. Its double indication system supports faster fault finding during planned or corrective maintenance.
Typical Applications
- Industrial low voltage power distribution.
- Main and sub-distribution switchboards.
- Motor control centres and machinery panels.
- Protection of high-current cables and conductors.
- Manufacturing and process equipment.
- Commercial and industrial electrical infrastructure.
