AEO 10.3x38: Automotive Fuse

With the AEO 10.3x38, SCHURTER launches 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.


Schurter Automotive Fuse


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.


Welding is more reliable

A weak point of every fuse is the connection between the melting wire and the contact cap. This is usually designed as a solder joint. In the fuse production process, however, this technology is not always 100 % error-free. Contact by means of welding is way more reliable. SCHURTER uses a new, patented process which guarantees highest reliability.


Versatile mounting options

The new fuses of the AEO series offer a multitude of possible mounting options. In addition to the mere fuse, which requires a fuse holder (recommended model: SCHURTER CSO) and the classic mounting directly on a printed circuit board, screwable lugs for surface mounting or even flush mounting (axial mount) are also available.


Unique Selling Proposition

  • Designed for electric vehicles (EV Car)
  • Very high rated current up to 50 A
