Sinofuse EV315-H-3EB10A Electric Vehicle Fuse, 10A 500V DC, High-Speed Bolt-on

The Sinofuse EV315-H-3EB10A is a precision-engineered high-speed fuse specifically designed for the protection of auxiliary circuits in Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). With a 10A current rating and 500V DC capability, this component is ideal for safeguarding low-power yet critical systems such as Air Conditioning (A/C) compressors, On-Board Chargers (OBC), and auxiliary Power Distribution Units (PDUs).

Designed to meet automotive reliability standards including JASO D622 and ISO 8820, this fuse features excellent resistance to thermal shock, mechanical vibration, and cyclic loading. Its high-speed clearing performance ensures a low let-through energy (I²t) profile, providing instantaneous protection against short-circuits and overcurrent faults in sensitive power electronic branch circuits. The bolt-on terminal design ensures a stable, low-resistance electrical connection, maintaining circuit integrity under harsh operating conditions.
