Why Choose the Mersen NH2GG50V100 NH Fuse-Link?
The Mersen NH2GG50V100 is a reliable DIN NH gG fuse-link designed to provide full-range protection against overloads and short circuits in low-voltage electrical distribution systems. Part of the established Mersen NH gG 500 V AC fuse-link series, it is suitable for protecting cables, feeder circuits, switchgear and industrial electrical equipment.
This fuse-link combines a high breaking capacity with effective current-limiting performance, helping reduce the thermal and mechanical effects of severe electrical faults. Its durable ceramic body, brass blade terminals and double indication system provide dependable operation and allow maintenance personnel to identify an operated fuse quickly.
With a rated current of 100 A, an AC voltage rating of 500 V and a DC voltage rating of 250 V, the NH2GG50V100 is suitable for industrial switchboards, commercial distribution systems and OEM electrical assemblies. Its standard NH Size 2 construction enables straightforward installation in compatible fuse bases and switch-disconnectors.

Reliable Protection for Low-Voltage Distribution Systems
The Mersen NH2GG50V100 protects electrical circuits by disconnecting sustained overload currents and high-level short-circuit faults before they can damage cables, switchgear or connected equipment. Its gG characteristic provides full-range protection, making it suitable for a broad range of general electrical distribution applications.
During a severe fault, the fuse-link limits the peak current and total energy allowed to pass through the circuit. This helps reduce thermal stress, mechanical forces and potential equipment damage while supporting safe and dependable operation.
