Spotlight on innovation: a new generation of high-performance AC/DC fuses
At a time when DC power systems are experiencing rapid growth, the need for efficient and simplified electrical protection solutions has become increasingly critical. Applications such as energy storage, EV charging infrastructure, data centers, and renewable energy systems demand optimized AC/DC performance and flexible integration.
To address these challenges, Mersen introduced at PCIM 2026 a new generation of high-performance fuses specifically designed to meet evolving market requirements.
A single fuse for AC and DC applications
These innovative fuses combine AC and DC electrical characteristics within a single compact housing, offering major benefits to equipment manufacturers:
- Space savings
- Simplified installation
- Reduced component complexity
- Streamlined procurement (one fuse instead of two)
The product range covers a wide spectrum of rated currents and can be used as:
- Standard AC fuses
- aR fuses
- Fast-acting fuses
Developed in close collaboration with leading players in energy storage, EV charging, and data center sectors, these fuses are fully aligned with real-world application requirements.
Designed for power conversion systems and beyond
The primary application for these high-performance fuses is power conversion systems, including inverters, transformers, and control units converting DC power (from solar or wind plants) into grid-compatible AC.
They are also ideally suited for:
- Data centers
- Energy storage systems
- EV charging infrastructure
For example, in data centers, these fuses help:
- Reduce system footprint
- Improve overall efficiency
- Enable more flexible power system design
Additionally, Mersen supports customers with simulation data, allowing precise adaptation of fuse behavior to specific applications.
Quality, Compliance and Performance
Manufactured on fully automated production lines, these high-performance fuses meet the latest international standards, including IEC 60269-4, UL, CCC, RoHS, REACH, and WEEE.
Each product undergoes rigorous testing, both in Mersen’s own laboratories and through external certification bodies, ensuring the highest levels of quality and reliability.
Driving the Future of Electrification
With the innovations presented at PCIM 2026 - particularly the launch of its new high-performance fuse range- Mersen reaffirms its commitment to delivering sustainable, efficient, and high-performance solutions for the power systems of tomorrow.
As electrification accelerates across industries, Mersen continues to support its customers with engineered solutions that combine safety, performance, and reliability.
