ADO Series for High-Voltage Automotive Applications

With the new ADO series from Schurter, we are expanding our portfolio to include reliable high-voltage DC fuses specifically designed for automotive applications.

These fuses are particularly suitable for electric vehicles and are used in a wide range of applications, including battery management systems, on-board chargers, DC/DC converters, air-conditioning compressors, PTC heating systems, and control units. The ADO series comprises 67 fuse variants with a rated current range from 10 A to 63 A and a maximum operating current of 40 A at 1,000 VDC. The fuses feature fast-acting characteristics and impress with their high current-carrying capacity and a breaking capacity of up to 50 kA. They offer a wide operating temperature range from –40 °C to +125 °C and a compact size of 10 × 38 mm. In addition, they are resistant to vibration and chemical exposure. Thanks to their patented filler formulation and specialized curing processes, the fuses ensure safe arc extinction and prevent secondary arcing.

The ADO fuse family offers four mounting options. In addition to the standard PCB-mount version, three screw-mount variants are available, providing secure fixation even under high vibration. Due to their low contact resistance, they are particularly suitable for high-current applications. Another advantage of the screw-mount versions is that they simplify fuse replacement and maintenance. The ADO series from Schurter is UL certified and complies with UL 248-20, ISO 8820-8, GB/T 31465.6, and JASO D622 standards.
