The Mersen NH2GG40V250 is a high-performance DIN NH gG fuse-link engineered to provide dependable full-range protection against overloads and short circuits in low-voltage electrical distribution systems. As part of the trusted Mersen NH gG 400 V AC fuse-link series, it is designed to protect cables, feeders, switchgear and industrial power distribution equipment in demanding commercial and industrial environments.
Designed in accordance with IEC standards, the NH2GG40V250 combines exceptional current-limiting performance with a high breaking capacity, helping minimise thermal and mechanical stress during fault conditions. Its robust ceramic body, double indication system and live gripping lugs ensure reliable operation while enabling rapid identification and safe replacement of an operated fuse.
With a rated current of 250 A and a rated voltage of 400 V AC, this NH Size 2 fuse-link is ideal for industrial switchboards, motor control centres, distribution panels and OEM electrical equipment. Its DIN-standard design ensures compatibility with standard NH Size 2 fuse bases and switch disconnectors.
The Mersen NH2GG40V250 provides reliable overcurrent protection by safely interrupting overloads and short-circuit faults before they can damage electrical equipment. Its gG characteristic makes it suitable for protecting cables, switchgear, distribution feeders and general-purpose low-voltage circuits.
Its excellent current limiting performance reduces thermal stress and electrodynamic forces during faults, helping improve equipment longevity while supporting safe and reliable operation in demanding industrial environments.
