Mersen NH3GG69V400

The NH fuse-link system is a plug-in fuse solution featuring components such as a fuse-base, which may include terminal covers and phase barriers, alongside a fuse-link with blade contact and a fuse-link replacement device (LV HRC fuse puller). Due to the design of this system, it is essential that a qualified professional handles it, as non-interchangeability of rated current cannot be assured.

These type gG NH fuse-links are designed with a full range breaking capacity, providing protection for cables and equipment. They can effectively interrupt current surges across a broad spectrum, from the lowest fusing current to their specified breaking capacity, allowing them to serve as standalone protection. Additionally, they safeguard electrical devices and industrial setups from the electrodynamic effects of high short-circuit currents.

With an ampere range of 2 to 500 A and compliance with standards such as DIN 57636 Part 201, VDE 0636 Part 201, and IEC 60269-1 and -2, these fuse-links are constructed from copper with silver-plated contacts and a ceramic body. The fuse-links meet CE conformity and are ROHS compliant, with applications focused on general purpose cable and line protection.
