Sinofuse EV315-H-3EB50A Electric Vehicle Fuse, 50A 500V DC, High-Speed Bolt-on - Pack of 10

The Sinofuse EV315-H-3EB50A is a professional-grade high-speed fuse engineered for the rigorous circuit protection requirements of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). With a 50A current rating and 500V DC capability, this fuse is designed to protect power electronic systems, including battery management systems, auxiliary power distribution, and inverter branch circuits.

Compliant with automotive reliability standards such as JASO D622 and ISO 8820, this component is built to endure harsh operating environments characterized by thermal shock, mechanical impact, and high-frequency vibration. The high-speed clearing performance provides rapid fault isolation with a low let-through energy (I²t) profile, ensuring superior protection against overcurrent and short-circuit events. The H-3EB bolt-on terminal design offers a robust, low-resistance mechanical connection, providing long-term electrical stability in critical vehicle power systems.
