Sinofuse EV315-M-3E10A Electric Vehicle Fuse, 10A 500V DC, Bolt-on High-Speed

The Sinofuse EV315-M-3E10A is a performance-oriented high-speed fuse designed for the rigorous demands of Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) circuit protection. With a 10A current rating and a 500V DC rating, this model is optimized for the protection of auxiliary systems, battery management units, and power distribution modules.

The "M-3E" designation specifies a bolt-down mounting configuration, which provides a secure, vibration-resistant mechanical connection essential for automotive environments. Unlike standard ferrule fuses, the bolt-on terminals ensure low contact resistance and stability under high-acceleration conditions. Manufactured in accordance with ISO 8820 and JASO D622, this fuse offers a breaking capacity of 20kA, effectively isolating faults to protect sensitive on-board semiconductor components.
