Mersen announces new 2017 DC overcurrent protection for EVs (Xp, Xs series)



January 11, 2017 – Mersen has new DC overcurrent protection solutions for electric vehicles and battery-related applications: the Xp and Xs series hybrid devices and an expanded line of DC fuses.

Mersen’s Xp Series’ heart is composed of a pyro-element with self-triggered and/or external ignition capacity. The Xs Series is a resettable 750 VDC arc-less hybrid power relay with the capability of switching both high voltage and high current. Mersen says both systems have been engineered to provide protection for DC applications: e-mobility, Electrical Energy Storage, EV/HEV, SmartGrid and PV installations.

Mersen’s EVpack-fuse (battery pack fuse) and M-fuse (battery module fuse) are designed to address specific needs in EV/HEV and battery storage systems. With e protection from 100 up to 1,000 VDC and up to 600A with Minimum Breaking Capacity (MBC) < 3kA, these fuse families have been tested in DC conditions to guarantee protection for large fault currents, the company adds.
