Sinofuse EV315-C-3E10A Electric Vehicle Fuse, 10A 500V DC, 10x38mm High-Speed Ferrule

The Sinofuse EV315-C-3E10A is a specialized high-speed ferrule fuse designed for the demanding electrical requirements of road vehicles, including Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). With a 10A current rating and a 500V DC voltage threshold, this fuse provides critical overcurrent protection for auxiliary circuits, onboard chargers (OBC), and power conversion units.

The "C-3E" designation refers to the cylindrical (ferrule) form factor, typically featuring a 10x38mm footprint. This design allows for standardized mounting in fuse clips or holders, offering a compact and reliable solution for protecting sensitive semiconductor devices. Engineered to operate under extreme automotive conditions, it offers high breaking capacity and low power dissipation to ensure system efficiency and safety.
