Why Choose the Mersen NH000GG69V25 NH Fuse-Link?
The Mersen NH000GG69V25 is a compact DIN NH gG fuse-link designed to provide full-range overload and short-circuit protection for cables, electrical equipment and low-voltage distribution circuits. As part of the Mersen NH gG 690 V AC fuse-link series, it is suitable for demanding industrial and commercial installations requiring dependable current limitation and fault interruption.
Its gG operating characteristic enables the fuse-link to interrupt currents ranging from low-level overloads through to high short-circuit currents. During a severe fault, its current-limiting action helps reduce the thermal and electrodynamic stress imposed on cables, switchgear and connected equipment.
With a rated current of 25 A, a rated voltage of 690 V AC and a 250 V DC rating, the NH000GG69V25 is suitable for industrial control panels, distribution boards and OEM electrical assemblies. Its compact NH000 construction, double indication system and live gripping lugs support convenient installation and maintenance in compatible DIN NH fuse equipment.

Reliable Protection for Cables and Electrical Equipment
The Mersen NH000GG69V25 protects electrical circuits by disconnecting sustained overload currents and high-level short-circuit faults before they can cause serious damage. Its full-range gG characteristic means that it can serve as the primary overcurrent protection device when correctly selected and installed.
During short-circuit conditions, the fuse-link limits the peak current and total energy passing through the circuit. This helps protect cables, busbars, switchgear and connected equipment from excessive heating and electrodynamic forces while supporting reliable electrical system operation.
