Sinofuse EV315-L-3EC20A Electric Vehicle Fuse, 20A 500V DC, High-Speed Bolt-on - Pack of 10

The Sinofuse EV315-L-3EC20A is a high-speed DC fuse specifically engineered for the advanced circuit protection requirements of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). Featuring a 20A current rating and a 500V DC voltage threshold, this fuse is optimized for safeguarding auxiliary power systems, including On-Board Chargers (OBC), DC/DC converters, and auxiliary Power Distribution Units (PDU).

Compliant with global automotive standards such as ISO 8820 and JASO D622, the EV315-L-3EC20A is built to withstand the rigorous demands of vehicle environments, including extreme mechanical shock, high-frequency vibration, and wide thermal fluctuations. Its high-speed clearing characteristics ensure rapid isolation of faults with minimal let-through energy (I²t), providing superior protection for sensitive semiconductor components. The 3EC bolt-on terminal ensures a secure, low-resistance connection that maintains electrical integrity over the vehicle's lifespan.
