Why Choose the Mersen NH2GG50V500 NH Fuse Link?
The Mersen NH2GG50V500 is a high-performance DIN NH gG fuse link designed to provide dependable overload and short-circuit protection for low-voltage electrical distribution systems. Manufactured by Mersen, this NH Size 2 fuse link is suitable for protecting cables, conductors, switchgear and connected electrical equipment in demanding industrial and commercial installations.
Featuring a rated current of 500 A, a rated voltage of 500 V AC and a rated voltage of 250 V DC, the NH2GG50V500 delivers full-range gG protection. This allows the fuse to respond to sustained overload conditions as well as severe short-circuit faults, helping reduce equipment damage and unplanned downtime.
The fuse is manufactured in the standard NH Size 2 format and incorporates plain blade contacts, live gripping lugs and a double operation indicator. Its robust ceramic body, 120 kA AC breaking capacity and standardised dimensions make it suitable for compatible NH fuse bases and switch-disconnectors used in industrial power distribution systems.

Reliable Protection for High-Current Distribution Systems
The Mersen NH2GG50V500 protects electrical circuits by interrupting excessive current before it can cause serious thermal or mechanical damage. Its full-range gG operating characteristic enables the fuse to protect cables and electrical equipment against both prolonged overloads and high-energy short-circuit faults.
The fuse’s current-limiting performance and high breaking capacity help reduce the energy allowed to pass during a fault. When correctly selected and installed, it can improve electrical safety, protect valuable equipment and minimise disruption within industrial power distribution systems.
Typical Applications
- Industrial low-voltage switchboards.
- High-current electrical distribution panels.
- Cable and conductor protection.
- Transformer secondary circuits.
- Industrial machinery power supplies.
- Commercial and industrial electrical installations.
