Key features & benefits

Electrification in construction, marine, agriculture, manufacturing, mining, and other industries, in addition to transportation, is a critical trend in cleaner energy. The D70QS North American style round body high-speed fuse series is Mersen’s next evolution for high-power conversion applications protection for those industries shifting to Direct Current(DC) systems today. The D70QS fuse series is specifically designed to reduce the I²t, peak let-through current, and arc voltages during fault conditions to protect applications such as battery charging systems and other DC components like relays and contactors.
