Mersen NH1GG69V200

The NH fuse-link system is categorized as a plug-in fuse arrangement, comprising a fuse base, which may include terminal covers and phase barriers, along with a fuse-link featuring blade contacts. A fuse-link replacement device, such as a low voltage high rupture capacity (LV HRC) fuse puller, is also included. Due to the design limitations that prevent the non-interchangeability of rated currents, the installation and handling of these components should be performed by qualified personnel.

Type gG NH fuse-links are characterized by their full-range breaking capacity, enabling them to safeguard both cables and equipment. They are capable of interrupting current surges ranging from the lowest fusing current to their maximum breaking capacity, enabling standalone application for protection purposes. Additionally, these fuse-links offer protection against the electrodynamic impacts of high short-circuit currents, which is critical for preserving the integrity of electrical devices and industrial setups.

This system adheres to several standards, including DIN 57636 Part 201, VDE 0636 Part 201, and IEC 60269-1 and -2. The fuse-links operate within an ampere range of 2 to 500 A and are constructed from ceramic material, with contacts made of copper and silver-plated components. Compliance with CE and ROHS regulations is also affirmed, ensuring their suitability for general-purpose cable and line protection applications.
