Mersen P223711

The NH fuse-link system is categorized under plug-in fuse systems, comprising a fuse-base, which may include terminal covers and phase barriers, alongside a fuse-link that utilizes blade contacts. The system requires handling by qualified professionals due to its design, which does not ensure non-interchangeability of rated currents.

Type 'gG' NH fuse-links offer full-range breaking capacity, ensuring protection for cables and equipment. They can interrupt current surges from their minimum fusing current up to their specified breaking capacity, enabling their use as standalone protection devices. These fuse-links further safeguard electrical devices and industrial setups against electrodynamic effects posed by high short-circuit currents.

The rated power dissipation for the Mersen NH fuse-links at 400VAC is maintained below the maximum thresholds established by IEC 60269 standards. This fuse-link features a body width of 30 mm and is constructed from ceramic insulating material, with silver-plated copper used for the connection terminals. Its specifications include an ampere rating of 125 A and a power dissipation value of 9.8 W, making it suitable for various industrial applications.
