Why Choose the Mersen NH1GG69V16 NH Fuse Link?
The Mersen NH1GG69V16 is a dependable DIN NH gG fuse link designed to provide full-range overload and short-circuit protection in low-voltage electrical distribution systems. Manufactured by Mersen, this NH Size 1 fuse link helps protect cables, conductors, switchgear, transformers and connected electrical equipment in demanding industrial and commercial installations.
Featuring a rated current of 16 A, a rated voltage of 690 V AC and a rated voltage of 400 V DC, the NH1GG69V16 is suitable for circuits requiring reliable protection at higher operating voltages. Its general-purpose gG operating characteristic provides protection across the full fuse operating range, covering both sustained overload conditions and severe short-circuit faults.
Manufactured in the standard NH Size 1 format, the fuse link features blade contacts, live gripping lugs, a double operation indicator and a body width of approximately 30 mm. Its standardised construction supports installation in compatible NH fuse bases and switch-disconnectors within industrial switchboards and power distribution equipment.

Reliable Protection for Electrical Distribution Systems
The Mersen NH1GG69V16 interrupts excessive current before it can cause serious damage to cables, switchgear or connected electrical equipment. Its full-range gG characteristic enables the fuse to respond to prolonged overloads as well as high-energy short-circuit faults.
Its current-limiting operation helps reduce the peak current and energy allowed to pass during a fault. When correctly selected and installed, the NH1GG69V16 can improve electrical safety, minimise equipment damage and reduce unplanned downtime in industrial distribution systems.
Typical Applications
- Industrial low-voltage switchboards.
- Electrical distribution panels.
- Cable and conductor protection.
- Transformer secondary circuits.
- Industrial machinery power supplies.
- Commercial and industrial electrical installations.
