Why Choose the Mersen NH000GG40V25 NH Fuse-Link?
The Mersen NH000GG40V25 is a premium NH size 000 gG fuse-link designed to provide full-range protection against overloads and short circuits in industrial electrical installations. Rated at 25 A and 400 V AC, it is ideal for protecting cables, conductors, switchgear and power distribution equipment in commercial and industrial applications.
Its gG utilisation category provides complete protection throughout the fuse-link's operating range. The NH000GG40V25 safely interrupts overload currents and high fault currents while its current-limiting performance helps reduce thermal and mechanical stress on downstream electrical equipment, improving system reliability.
Manufactured to the DIN NH standard, the fuse-link incorporates a durable ceramic body, silver-plated copper blade contacts, live gripping lugs and a double indication system. Its compact NH000 design enables straightforward installation into compatible NH fuse bases, fuse-switch disconnectors and industrial power distribution equipment.
