The EV1K Series Fuse is designed specifically for automotive-grade solutions applications. It provides overcurrent protection in applications connected to Electric Vehicles' high voltage power supply. With a rating of 1000 Vdc, the fuse is currently available in amperage ratings of 60 to 125 A (ratings up to 600 A are forthcoming). It uses a bolt-down form factor with a 25 mm x 73 mm cartridge body. The certification testing for this fuse uses the ISO 8820 and LV standards to ensure it is compatible with the Automotive environment (thermal shock/cycling, vibration, etc.).
