Mersen-high-performance-fuse
As an expert in electrical protection, Mersen is presenting its latest generation of high-performance fuses at PCIM 2026. The products offer optimized AC/DC performance and were specifically designed for the rapidly growing DC power systems market, while maintaining the fast-acting performance of Mersen AC legacy fuses. Mersen developed the high-performance fuses in close collaboration with leading companies in the fields of energy storage, electric vehicle charging infrastructure, and data centers.
A New Generation of High-Performance AC/DC Fuses
The high-performance fuses combine the best AC/DC electrical characteristics in a single compact housing. This design not only saves space for equipment manufacturers and offers great flexibility in installation – it also significantly simplifies their procurement process. Whereas they previously needed two different fuse types for AC and DC applications, only one is now required. The product range covers a very wide range of rated currents, and the fuses can be used as standard AC fuses, AR fuses, or fast-acting fuses.
Designed for Power Conversion and Key Applications
Developed in close collaboration with leading companies, these high-performance fuses are fully aligned with real-world application requirements. The primary application area for Mersen’s new high-performance fuses is power electronics, power conversion systems like but not limited to inverters, SST, CS, and MCS. These systems convert direct current – e.g., from PV and wind energy plants – into grid-compatible alternating current. All high-performance fuses undergo rigorous quality testing, most of which is conducted in Mersen’s own UL-recognized test laboratory and external specialized institutes. The new high-performance fuses are manufactured on fully automated production lines in accordance with the latest technical standards (IEC, UL, CCC, RoHS, REACH, WEEE).
Mersen’s latest design was developed with a focus on improving quality while streamlining manufacturing and strengthening supply chain efficiency. Mersen also provides users with a range of data from simulation processes that demonstrate the fuse’s behavior in a customer-specific application. This allows the products to be optimally selected to match end-users' respective requirements. With the launch of the new high-performance fuses, with two new sizes released to address emerging DC applications up to 1000 V/1000 A, Mersen underscores its commitment to offering sustainable, high-performance, and efficient solutions for today and future applications.
