Sinofuse EV315-L-3EC10A Electric Vehicle Fuse, 10A 500V DC, High-Speed Bolt-on - Pack of 10

The Sinofuse EV315-L-3EC10A is a precision-engineered high-speed DC fuse designed for the sensitive circuit protection requirements of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). With a 10A current rating and a 500V DC voltage rating, this component is optimized for protecting low-power auxiliary circuits, including On-Board Chargers (OBC), DC/DC converters, and battery monitoring systems (BMS).

Developed to meet rigorous automotive standards such as ISO 8820 and JASO D622, the EV315-L-3EC10A is built to perform reliably under extreme conditions, including high vibration, mechanical shock, and significant thermal cycling. Its high-speed clearing capability ensures minimal let-through energy (I²t) during a fault, providing critical protection for semiconductor devices and other sensitive power electronics. The "3EC" bolt-on terminal configuration provides a secure, vibration-resistant electrical connection, ensuring long-term contact integrity in demanding automotive environments.
