Sinofuse EV315-M-5N-500A Electric Vehicle Fuse, 500A 500V DC, High-Speed Bolt-on

The Sinofuse EV315-M-5N-500A is a heavy-duty high-speed DC protection fuse engineered for high-power Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) applications. With a robust 500A current rating and 500V DC voltage capacity, this component is designed to provide primary circuit protection for high-capacity lithium battery packs, large traction inverters, and heavy-duty Power Distribution Units (PDUs).

Equipped with the "M-5N" bolt-on terminal configuration, this fuse offers superior mechanical stability and low contact resistance, specifically optimized to withstand the high-vibration and thermal-shock environments of automotive and industrial transportation. Its advanced semiconductor protection characteristics ensure extremely fast response times and low let-through energy (I²t), effectively preventing damage to high-value power electronic components during short-circuit or massive overcurrent events. This series is a critical safety component for manufacturers focusing on high-reliability energy storage and vehicle electrification.
