Sinofuse EV315-C-3E30A Electric Vehicle Fuse, 30A 500V DC, 10x38mm High-Speed Ferrule

The Sinofuse EV315-C-3E30A is a professional-grade high-speed cylindrical fuse engineered for the protection of Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) systems. Rated at 30A with a 500V DC voltage capacity, it is designed to safeguard power conversion systems, battery management units, and on-board charging equipment from short-circuit and overcurrent events.

Constructed as a 10x38mm ferrule type, this fuse is optimized for high-density automotive power distribution modules. It features exceptional resistance to mechanical vibration, thermal shock, and chemical loads, meeting the stringent requirements of the road vehicle industry. With its low I²t clearing values and a 20kA breaking capacity, it ensures rapid interruption to protect sensitive semiconductor power electronics.
