100kA Breaking Capacity & UL/CE Certified

Our battery fuses feature an advanced fusible element that achieves response times of less than 1 millisecond under severe faults. This rapid action limits the peak current (let-through) to the lowest possible level, protecting sensitive electronic components such as MOSFETs and IGBTs. In real-world applications, this means less potential damage to devices and reduced downtime. For example, a DC microgrid project in Japan used our fuses to protect power converters, and they successfully prevented cascading failures during grid disturbances. The fuses' design also incorporates a patented arc-quenching technology, which safely extinguishes arcs within milliseconds, minimizing thermal stress and extending the overall lifespan of the system. In rigorous testing, our fuses consistently perform above the requirements of IEC 60269 standards.

Safety is paramount in battery systems, and our fuses are designed to break fault currents up to 100kA, preventing catastrophic failures. The low voltage drop (under 85mV at rated current) reduces power loss and heat generation, improving overall system efficiency. This is especially advantageous in high-current battery packs used in electric vehicles, where every watt-hour counts. We have conducted extensive tests that show our fuses maintain a stable temperature rise under continuous current, which extends the fuse's life and prevents nuisance tripping. Additionally, the incorporation of silver and copper elements ensures reliable conductivity that is better than industry standard. Our fuses are also environmentally friendly, being 100% recyclable and RoHS compliant.
