In battery and battery system the fuses are required to operate in DC systems which may have high fault currents and a number of lower overcurrent situations. Another challenge is the tendency of further higher voltage levels.
There is a new proposed standard for these specific requirements, IEC60269-7. It includes two new utilisation classes, gBat (full range protection) and aBat (partial range protection, short circuit protection only).
Eaton Bussmann Series introduce four new fuses based on the draft for the new standard.
