Square Body High-Speed Fuse Protistor® Size 302 aR 1800VDC IEC 300A Striker L Brackets
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.
