Why Choose the Mersen NH2GG69V250 NH Fuse Link?
The Mersen NH2GG69V250 is a high-performance DIN NH gG fuse link designed to provide full-range protection for low-voltage cables, conductors and industrial electrical equipment. Manufactured by Mersen, this NH2 fuse link protects electrical circuits against both sustained overloads and high prospective short-circuit currents.
As part of the proven Mersen NH gG 690 V AC fuse range, the NH2GG69V250 combines strong current-limiting performance with a high fault-interruption capability. This helps reduce the thermal and electrodynamic stresses placed on cables, busbars, switchgear and connected equipment during electrical faults.
With a rated current of 250 A, a 690 V AC rating and a 250 V DC rating, the NH2GG69V250 is ideal for industrial switchboards, distribution panels and high-capacity feeder circuits. Its double indication system and live gripping lugs support quick fuse-status identification and efficient replacement by qualified electrical personnel.

Reliable Protection for Industrial Distribution Systems
The Mersen NH2GG69V250 uses a full-range gG time-current characteristic, allowing it to protect circuits against low-level sustained overloads as well as severe short-circuit faults. This means it can be used as the principal protective fuse for appropriately rated cables, conductors and general-purpose electrical equipment.
During a high-current fault, the fuse link limits the peak current and the amount of energy passed into the electrical system. This helps reduce damage to switchgear, busbars, cables and connected equipment. Installation and replacement should only be completed by qualified electrical personnel using appropriate NH fuse-handling equipment.
Typical Applications
- Industrial switchboards and distribution panels.
- Low-voltage cable and conductor protection.
- High-capacity feeder circuits.
- Commercial electrical distribution systems.
- Industrial machinery power supplies.
- Infrastructure and utility installations.
