Blade Fuses MICRO3™ Blade Fuses Rated 32V The MICRO3™ Fuse has 3 terminals and 2 fuse elements with a common center terminal. Its sub-miniature design meets the need for more circuits to be protected while utilizing less space and its ability to cope with high temperatures in adverse environments makes the MICRO3™ Fuse of recommended choice for protection. Specifications Voltage Rating: 32 VDC Interrupting Ratings: 1000A @ 32 VDC *Component Level Temperature Range: -40˚C to +125˚C **System Level Temperature Range: -40˚C to +105˚C 105°C is a typical system level temperature requirement.

This does not factor-in the heat from a populated fuse box, but does include the heat from the current load with the proper rerating. **System Level Temperature represents the ambient temperature of the fuse box at a location within the vehicle. The temperature within a populated fuse box (in a given location) will be higher. The limiting factor is the plating. Sn-plating’s temperature limit is ≈130°C, and Ag-plating allows up to 150°C at the terminal interface.
