Why Choose the Mersen NH000GG50V20 NH Fuse-Link?
The Mersen NH000GG50V20 is a compact DIN NH gG fuse-link designed to provide reliable full-range protection for cables, conductors and low-voltage electrical equipment. With a 20 A rated current, a 500 V AC rating and a 250 V DC rating, it is suitable for industrial and commercial power distribution applications.
Manufactured in the compact NH000 blade-contact format, the NH000GG50V20 can be installed in compatible NH fuse bases and switch-fuse assemblies. Its gG operating characteristic provides protection against sustained overloads and high short-circuit currents, helping prevent damage to cables, switchgear and connected electrical equipment.
The fuse features a robust ceramic body, plain brass blade terminals, live gripping tags and a double visual indicator. Its high 120 kA AC breaking capacity enables dependable interruption of substantial prospective fault currents in demanding low-voltage installations.

Reliable Protection for Low-Voltage Circuits
The Mersen NH000GG50V20 protects cables and connected equipment by interrupting excessive current before damaging thermal and mechanical stresses can develop. Its gG characteristic provides full-range protection against both prolonged overload conditions and high-level short circuits.
The fuse’s current-limiting design helps reduce the fault energy transmitted to downstream conductors, busbars and switchgear. Its compact NH000 construction makes it particularly suitable for installations where panel space is limited, while the double indicator supports efficient fault finding and maintenance.
