SCHURTER presents ALO EV Fuse: compact high-capacity fuses for power electronics in automotive applications
At RC Microelectronics, official distributor of SCHURTER in Spain and Portugal, we present the ALO EV Fuse — a high breaking capacity fuse (up to 50 kA @ 1000 VDC) specifically developed for power electronics applications in electric vehicles. This fuse combines a compact design with maximum reliability and safety, meeting the most demanding requirements of the automotive industry.
ALO EV Fuse: top-level safety and performance
The ALO EV Fuse stands out for its ability to withstand voltages up to 1000 VDC and rated currents between 100 and 900 A. Its axial design with bottom screw mounting enables easy integration into power distribution units (PDUs), battery disconnect units (BDUs), battery management systems (BMS), and all-in-one controllers or 2-in-1 electric propulsion systems.
Made with high-quality materials (nickel-plated copper alloy terminals, ceramic/resin tube, and copper end caps), this fuse offers exceptional resistance to vibration and mechanical shock according to MIL-STD-202, as well as tolerance to chemical loads and an operating temperature range from –40 °C to +125 °C. Additionally, it can be stored between –40 °C and +70 °C with a maximum relative humidity of 70 %, while maintaining its electrical and mechanical properties intact.
Advantages and applications
The ALO EV Fuse offers clear advantages over conventional solutions:
- Very high breaking capacity, up to 50 kA, ensuring protection against severe short circuits.
- Compact size, enabling integration into systems where space is critical.
- High reliability and safety, meeting international vibration and shock standards.
- Easy screw mounting, adaptable to various electric vehicle configurations.
It is recommended for use in critical power electronics applications, including PDUs, BDUs, BMSs, and integrated electric propulsion control systems.
