The HV fuse is part of the Limitor®-P product line, specifically designed as a back-up fuse for transformers, adhering to the IEC 60282-1 standard. This fuse ensures reliable protection against short-circuit currents in high-voltage switchgear and control systems.Constructed with high-quality materials, the fuse elements are made of pure silver, while the caps are copper plated with silver. The ceramic body offers effective insulation, contributing to the fuse’s robust performance. With a rated voltage of 24 kV and an ampere rating of 160 A, this fuse is optimized for high-voltage applications.The breaking capacity of 40 kA and a minimum interrupting rating of 900 A make it suitable for demanding environments. Additionally, the fuse features a cylindrical connection terminal made of silver-plated copper, facilitating secure mounting with a clip mechanism. The dimensions of the fuse are d=88mm and L=442mm, with a clearing I²T at rated voltage of 500 kA²s and a power dissipation of 515 W.

The NH fuse-link system is a plug-in fuse solution that includes a fuse base, which may feature terminal covers and phase barriers, along with a fuse-link equipped with blade contacts. A fuse-link replacement device, specifically an LV HRC fuse puller, is also part of this system. Due to the design characteristics, it is necessary for a qualified professional to handle the installation, as the system does not guarantee non-interchangeability of rated currents.Type gG NH fuse-links are full-range breaking capacity devices utilized primarily for the protection of cables and equipment. They are capable of interrupting current surges from the lowest fusing current up to their specified breaking capacity, allowing them to function independently as protective devices. Additionally, they safeguard electrical equipment and industrial setups from the electrodynamic effects that arise from very high short-circuit currents.
