Sinofuse EV315-M-5M-175A Electric Vehicle Fuse, 175A 500V DC, High-Speed Bolt-on - Pack of 3

The Sinofuse EV315-M-5M-175A is a high-performance, high-speed automotive fuse designed for the rigorous demands of Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) power systems. Rated at 175A and 500V DC, this fuse is specifically engineered to provide ultimate short-circuit and overcurrent protection for main traction battery packs, Power Distribution Units (PDU), and high-power motor drives.

Featuring a robust ceramic body and a specialized "M-5M" bolt-down terminal configuration, this unit ensures low-resistance electrical contact and exceptional resistance to mechanical shock and vibration. Its high-speed clearing characteristics are optimized to limit let-through energy (I²t), preventing cascading failures in sensitive power electronic components. The EV315 series is manufactured in accordance with strict automotive standards, including ISO 8820 and JASO D622, ensuring safety and reliability in critical transportation applications.
