High Performance Fuse for Automotive Applications Reliable Protection for High-Voltage Systems in Electric Vehicles

SCHURTER presents the AMO 10.3×38 – a high-performance fuse designed for demanding automotive applications. It reliably protects high-voltage systems up to 800 VDC and 50 A, making it ideal for BMS (Battery Management Systems), DC-DC converters and on-board / off-board chargers. With innovative welding technology and versatile mounting options, the AMO series sets new standards in safety and reliability.

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. This in order to meet customer requirements concerning driving performance and range by still providing the shortest possible recharging times. To safeguard this level of power, you need highly reliable high power fuses. Such fuses are required, for example, in the BMS (Battery Management System), for 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 connection is usually done by a solder joint. In the fuse production process, however, this technology brings quite many difficulties. Creating the connection by welding increases the reliability by far. SCHURTER uses a new, patented process which guarantees highest reliability.

Versatile mounting options
The new fuses of the AMO series offer a multitude of possible mounting options. In addition to the classic mounting directly on a printed circuit board, screwable version for surface mounting or even axial mounting are available.
