Why Choose the Mersen NH00GG50V63 NH Fuse-Link?
The Mersen NH00GG50V63 is a high-performance DIN NH size 00 gG fuse-link designed to provide dependable full-range protection for cables, conductors and electrical equipment in low voltage distribution systems. Rated at 63 A and 500 V AC, it is suitable for industrial switchboards, feeder circuits, machinery and commercial electrical installations.
Its gG utilisation category enables the fuse-link to protect against both sustained overload currents and severe short-circuit faults. The current-limiting construction rapidly restricts peak fault current and let-through energy, helping reduce thermal and electrodynamic stress on cables, switchgear and connected equipment.
The NH00GG50V63 features a robust ceramic body, standard blade contacts, live gripping lugs and a double indication system that assists with identifying an operated fuse-link. It is designed for installation in compatible NH size 00 fuse bases and fuse-switch disconnectors by suitably qualified electrical professionals.

Reliable Full-Range Circuit Protection
The gG operating characteristic provides comprehensive protection across the complete overcurrent range, from prolonged overload conditions through to high prospective short-circuit currents. During a major fault, the fuse-link interrupts the circuit quickly and limits the energy passed into the installation.
The Mersen NH00GG50V63 is well suited to coordinated protection within industrial and commercial low voltage systems. Correct selection should take account of conductor capacity, operating load, system voltage, prospective fault current and coordination with upstream and downstream protective devices.
Typical Applications
- Industrial cable and conductor protection.
- Low voltage distribution switchboards.
- Feeder and sub-distribution circuits.
- Machinery and manufacturing equipment.
- Commercial electrical installations.
- NH fuse bases and fuse-switch disconnectors.
