DC High Performance Square and Round Body

Electrification in construction, marine, agriculture, manufacturing, mining, and other industries, in addition to transportation, is a critical trend in cleaner energy. The D100QS North American style round body highspeed fuse series is Mersen’s next evolution for high-power conversion applications protection for those industries shifting to Direct Current (DC) systems today. The D100QS 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.

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.

Mersen DC fuses offer high-performance solutions designed specifically for railway power circuit protection, ensuring service continuity in transportation networks.
Based on our expertise, Mersen DC high-speed fuses have been engineered to provide improved performance, required by modern DC embedded equipment.
Compared to conventional fuse types:
- they are qualified under IEC 60077-5 for use in harsh environments (shock, vibrations...) and are dedicated to rolling stock applications,
- they provide lower I²t, minimizing damage to protected components during short circuits,
- they have lower watt losses and longer lifetime.
Our Application Engineering team remains at your disposal for any additional information or support tailored to your specific needs.

Mersen DC offers provide a very high performant protection for DC
applications in particular battery container or inverter protection.
ABAT15C fuses have been designed for applications up to 1500VDC, with current ratings from 500A to 1250A.

This range is compliant with IEC 60269-7, a new standard dedicated
for battery protection.

ABAT15C fuses allow them to clear high Max. Interrupting Rating and
provide a limited power loss.

This range is CE (manufactured in France) and UL/CSA Recognized.

Mersen DC offers provide a very high performant protection for railway power and auxiliary circuits. Mersen DC Semiconductor fuse-links were developed to provide improved performance required by today's new DC equipment. These fuse-links are typically operated at more elevated temperature than other fuse type, have lower I²t to minimize damage to protected components on short circuits, lower watts loss and longer life.
