Automotive fuse designed for electric vehicles

With the AEO 10.3×38, Schurter launched a high-performance fuse for particularly high voltages up to 1000 VDC and currents up to 50 A, which is particularly suitable for demanding automotive applications.

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. First and foremost in order to meet customer requirements in terms of driving performance and range with the shortest possible charging times. To safeguard such outputs, correspondingly resilient and highly reliable fuses are required. They are used, for example, in the BMS (Battery Management System), on-board and off-board chargers. DC-DC converters and other systems exposed to high voltages.
