Overview

The Mersen NH0GG50V25-1 (SKU: P214672) is a high-reliability NH Standard fuse-link designed for comprehensive protection of electrical systems. This gG type fuse-link offers full-range breaking capacity, capable of interrupting any current surge from the lowest fusing current up to its rated breaking capacity. It is specifically engineered to protect cables and equipment from both overload conditions and the severe electrodynamic effects of very high short-circuit currents. This NH0 size fuse-link operates at a rated voltage of 500VAC (IEC) and 250VDC (IEC), with a rated current of 25A. It features isolated gripping-lugs for safe handling and a double indicator system that clearly signals when the fuse has operated. The body width is 30 mm, and it has a power dissipation of 2.4W at its rated current. The NH system, to which this fuse-link belongs, is a plug-in fuse system comprising a fuse-base, the fuse-link itself with blade contacts, and a fuse-link replacement device (LV HRC fuse puller). Due to the design not guaranteeing non-interchangeability of rated current, it is crucial that this system is handled by qualified professionals. Applications for the Mersen NH0GG50V25-1 include general purpose protection of cables, busbars, and equipment in industrial settings, ensuring operational continuity and safety. Its robust construction and adherence to IEC standards make it a dependable choice for critical infrastructure. The product originates from France (FR).
