The Mersen NH000GG50V20-1 is a compact and dependable DIN NH gG low-voltage fuse link designed to protect industrial cables, electrical equipment and power distribution circuits against overloads and short circuits. Manufactured by Mersen, this full-range fuse link provides reliable current limitation and fault interruption for demanding commercial and industrial electrical installations.
The NH000GG50V20-1 features isolated gripping lugs and a double operating indicator. The isolated tags support safer handling by qualified electrical personnel, while the indication system allows an operated fuse to be identified quickly during inspection, troubleshooting and maintenance.
With a rated current of 20 A, an AC voltage rating of 500 V and a DC voltage rating of 250 V, this compact NH000 fuse link is suitable for industrial switchboards, distribution panels, machinery and automation systems requiring reliable general-purpose circuit protection.
Type gG fuse links provide full-range protection by interrupting both overload currents and high short circuit currents. This helps protect conductors, switchgear and connected electrical equipment while limiting the thermal and electrodynamic damage associated with electrical faults.
The Mersen NH000GG50V20-1 is designed for installation in compatible NH fuse bases and switchgear assemblies. Its compact dimensions make it particularly suitable for space-conscious electrical panels, although installation and replacement should only be completed by qualified electrical personnel using appropriate protective equipment.
