Mersen T223002

The NH fuse-link aM operates within a plug-in fuse system framework, consisting of a fuse-base, which may include terminal covers and phase barriers, a fuse-link with blade contact, and a fuse-link replacement device, specifically a low-voltage HRC fuse puller. This system is not designed to ensure non-interchangeability of rated currents, necessitating handling by qualified professionals.

This variant is rated for a maximum voltage of 690 V AC and has an ampere rating of 250 A. It features a breaking capacity of 80 kA, allowing it to effectively interrupt high fault currents. The power dissipation at the rated current value is measured at 21.5 W, ensuring reliable thermal management during operation. The ceramic insulating material used in the body enhances durability, while the connection terminals are composed of silver-plated copper for optimal conductivity.

Notably, the NH1 size and aM speed characteristic make this fuse-link suitable for a range of applications where reliable overcurrent protection is essential. To maintain performance, installation should adhere to the specified mounting method, which is clip-based.
