Mersen NH000GG40V50-1 DIN NH000 gG fuse link rated at 50 A and 400 V AC, featuring isolated gripping tags, double indication and a 100 kA breaking capacity.
£8.15
The Mersen NH000GG40V50-1, manufacturer item number A223698, is a compact NH000 gG fuse link designed to provide full-range overcurrent protection for cables, electrical equipment and low-voltage power distribution systems. Manufactured by Mersen, this DIN-standard fuse link combines dependable fault interruption with a space-saving 21 mm body width for use in compatible NH fuse bases.
Rated at 50 A and 400 V AC, the NH000GG40V50-1 has a gG operating characteristic. This enables it to protect circuits against both sustained overload currents and high-level short-circuit faults, making it suitable for general-purpose cable, line and equipment protection.
The fuse features isolated gripping tags and a double-indicator system to support safer handling and straightforward identification of an operated fuse. Its ceramic body and silver-plated copper blade contacts provide excellent electrical insulation, thermal durability and reliable conductivity in industrial and commercial installations.
The Mersen NH000GG40V50-1 provides full-range circuit protection by interrupting overload currents as well as severe short-circuit faults. Its gG characteristic makes it suitable for protecting power cables, conductors, switchgear and general electrical equipment without requiring a separate short-circuit protection fuse.
The high 100 kA breaking capacity enables the fuse to safely interrupt substantial prospective fault currents when correctly selected and installed. For safety, NH fuse links should only be fitted or removed by qualified personnel using an appropriate low-voltage HRC fuse puller and approved isolation procedures.
