Mersen NH3GG50V630-1

The NH fuse-link system is a plug-in type that includes essential components such as a fuse-base, which may feature terminal covers and phase barriers, along with a fuse-link equipped with blade contact. Additionally, a fuse-link replacement device (LV HRC fuse puller) is part of the setup. Due to design considerations, it is crucial that handling is performed by qualified personnel to ensure proper functionality and safety.

These type gG NH fuse-links are characterized by their full range breaking capacity, meaning they can effectively protect cables and equipment against current surges from the minimum fusing current up to their specified breaking capacity. This makes them suitable for standalone protective applications. Furthermore, they are adept at safeguarding electrical devices and industrial configurations from the electrodynamic impacts of substantial short-circuit currents.

Applications include general purpose cable and line protection, utilizing materials such as copper and silver-plated contacts, while complying with standards such as VDE 0636 Part 201 and IEC 60269-1 and -2. The ampere range spans from 2 to 630 A, ensuring versatility in various settings. The body of the fuse-link is made from ceramic, contributing to its durability and reliability.
