Why Choose the Mersen NH000GG69V80 NH Fuse Link?
The Mersen NH000GG69V80 is a compact, high-performance DIN NH gG fuse link designed to provide full-range overload and short-circuit protection for low-voltage electrical distribution systems. Manufactured by Mersen, this industrial fuse link helps protect cables, conductors, switchgear and connected electrical equipment against damaging overcurrents.
Featuring an 80 A rated current, a 690 V AC rating and a 250 V DC rating, the NH000GG69V80 is suitable for demanding industrial and commercial power systems. Its general-purpose gG operating characteristic enables the fuse to interrupt currents throughout its full operating range, from sustained overloads to severe short-circuit faults.
The compact NH000 format has a body width of approximately 21 mm and includes blade contacts, live gripping lugs and a double operation indicator. Its standardised design supports installation in compatible NH fuse bases and switch-disconnectors within control panels, switchboards and industrial distribution equipment.

Reliable Protection for Electrical Distribution Systems
The Mersen NH000GG69V80 protects electrical circuits by interrupting excessive current before it can cause serious damage to cables, switchgear or connected equipment. Its full-range gG characteristic provides protection against both prolonged overload conditions and high-energy short-circuit faults.
The fuse link also limits the electrodynamic and thermal effects associated with high fault currents. When correctly selected and installed, it helps improve electrical safety, reduce equipment damage and minimise unplanned downtime in industrial power systems.
Typical Applications
- Industrial low-voltage switchboards.
- Electrical distribution panels.
- Cable and conductor protection.
- Industrial machinery power circuits.
- Transformer secondary circuits.
- Commercial and industrial power installations.
