As the demand for fast charging of heavy-duty electric vehicles grows, high-power solutions are essential to reduce charging times efficiently.
With decades of expertise in high-performance electrical protection, Mersen offers a dedicated range of DC fuses delivering exceptional safety and reliability for MCS applications.
ABAT13C DC Fuses are designed for applications up to 1250Vdc, with current ratings from 500A to 1250A.

This range complies with IEC 61851-23-3, the upcoming standard for DC charging systems ≥ 1 MW, developed in collaboration with the CharIN group.

The NH system is classified among plug-in fuse systems and is composed of:
* fuse-base (possibly including terminal covers and phase barriers)
* fuse-link with blade contact
* fuse-link replacement device (LV HRC fuse puller)
Since the design of this system cannot guarantee non-interchangeability of rated current it must be handled by a qualified professional.

Type "aM" NH fuse-links are partial-range breaking capacity fuse-links, used to protect motor circuits as they are strongly current-limiting and have low power losses. They interrupt currents from 6.3 times In up to their maximum breaking capacity and are therefore suited for short-circuit protection only. They must be associated with other switchgear for protection against overloads. These fuse-links can have a rated current equal to the motor's nominal current.
