AEO Series 10.3 mm x 38 mm Midget-fuse for EV Automotive Applications

SCHURTER's AEO 10.3 mm x 38 mm midget-fuse series is particularly suited for battery protection in electric vehicles. The AEO series safely interrupts short circuits up to 20 kA at 1,000/800 V_DC with a current rating range of 10 A to 50 A. The series offers mounting versatility in addition to its remarkable high performance.

High voltages and high currents occur in electric vehicles in numerous places. Their battery packs with several thousand rechargeable cells store enormous amounts of energy in order to provide for the demands of drive performance and distance with the shortest possible charging times. Such applications require highly reliable fuses to safeguard such power. They are used, for example, in battery management systems (BMS), on-board and off-board chargers, DC-DC converters, and other systems exposed to high voltages.

Fuses produced with solder connections between the melting wire and contact caps are considered to have an inherent weakness in the solder joints; the production process for this type of technology is not always 100% error-free. Welding the contacts is a more reliable method and SCHURTER's patented welding process guarantees the highest reliability.

The AEO series fuse meets reliability specifications according to AEC-Q200 and is UL approved. Mounting options include compatibility with SCHURTER's heavy duty CSO fuse clip designed for voltages up to 1500 V_DC and currents up to 32 A. Other options include in-line axial terminals for wire connections, through-hole PCB mounting, or screw mount PCB.
