gBat NH fuse links 440V/550V DC

Battery storage protection fuse links

gBat NH fuse links are specially designed to protect battery systems according to the Standard IEC60269-7.

gBat NH fuse links are capable to clearing all types of overcurrents, overloads and short-circuits, thus the fuse links protect the batteries as well as cables and all switchgear of installation.

These fuse links are designed and manufactured with the same techniques that semiconductor fuse links, which makes them very fast of operation and gives a good performance under continuous charge/discharge cycles.

They are optimized to have reduced power dissipations that allow the utilization of a wide range of fuse bases, disconnectors and fuse switch disconnectors.

BATTERY NH fuse links range comprise five sizes NH000, NH00, NH1, NH2 and NH3 with rated currents between 20A and 630A, with working voltages up to 440V DC or 550V DC.
