Why Choose the Mersen NH0GG50V20 NH Fuse-Link?
The Mersen NH0GG50V20 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. As part of the established Mersen NH gG 500 V AC fuse-link range, it offers dependable current limitation for cables, switchgear and industrial electrical equipment.
This NH0 fuse-link features double visual indicators and live gripping lugs. The indicators allow maintenance personnel to identify an operated fuse quickly, while the standard blade-contact construction enables installation in compatible DIN NH fuse bases and fuse-switch disconnectors.
With a rated current of 20 A, an AC voltage rating of 500 V and a DC voltage rating of 250 V, the NH0GG50V20 is suitable for protecting conductors, distribution circuits and general-purpose industrial loads. Its gG characteristic provides complete protection across both overload and short-circuit operating regions.

Reliable Protection for Electrical Distribution Systems
The Mersen NH0GG50V20 provides complete protection across the full fault-current range. Its gG characteristic responds to sustained overloads as well as high short-circuit currents, helping protect cables, conductors, switchgear and connected electrical equipment.
Its current-limiting construction restricts the peak current and energy passed during a fault, reducing thermal and mechanical stress on downstream equipment. The DIN NH format also allows straightforward integration into compatible industrial fuse bases and switch-disconnector assemblies.
Typical Applications
- Low voltage power distribution systems.
- Industrial switchboards and control panels.
- Cable and conductor protection.
- Commercial distribution boards.
- Machinery and OEM electrical equipment.
- Fuse-switch disconnectors and NH fuse bases.
