Sinofuse EV315-M-5M-350A Electric Vehicle Fuse, 350A 500V DC, High-Speed Bolt-on - Pack of 3

The Sinofuse EV315-M-5M-350A is a professional-grade high-speed DC fuse specifically engineered for the high-power circuit protection requirements of modern Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). With a robust 350A current rating at 500V DC, this fuse is an essential safety component for large-scale battery systems, traction inverters, and high-voltage Power Distribution Units (PDUs).

Designed for the automotive environment, the "M-5M" bolt-on configuration provides a stable and secure connection capable of withstanding severe mechanical vibrations and high thermal shock. The EV315 series features optimized energy-limiting capabilities, ensuring low let-through energy (I²t) during a fault condition to prevent damage to expensive power semiconductors and battery modules. This series is a trusted selection for Tier-1 automotive suppliers and developers of high-capacity energy storage systems worldwide.
