ADO – Automotive Fuse for High Voltages

The new SCHURTER ADO series is a fuse with a rated current range of 10 to 63 A and a maximum operating current of 40 A at 1000 VDC. It is designed for applications in direct current systems up to 1000 VDC and is particularly suitable for use in electric vehicles.

The fuse has a fast tripping characteristic, high current carrying capacity and good vibration resistance. The ADO series is UL-certified. Technological features such as a patented filler formulation and special curing processes ensure safe arc extinguishing and prevent secondary arcing.

Mounting Options
A total of 4 mounting options are provided in the SCHURTER ADO fuse family. In addition to a conventional variant for PCB assembly, there are 3 for screw mounting. The screw variants ensure a firm, mechanical fit even in the event of strong vibrations. They are also ideal for applications where high currents flow, as the contact resistance is low. The screw variant also offers advantages in terms of maintenance (can be replaced after tripping).

Application Areas
The new ADO fuse family has been specially developed for applications in the automotive sector. The possible applications are very diverse. These include battery management systems, onboard chargers, DC/DC converters, air conditioning compressors and PTC heating systems as well as various control systems (e.g. motor control).
