Sinofuse EV315-3EN15A Electric Vehicle Fuse, 15A 500V DC, High-Speed Bolt-on - Pack of 10

The Sinofuse EV315-3EN15A is a high-performance DC fuse specifically engineered for the overcurrent protection of Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) systems. Rated at 15A and 500V DC, this fuse is designed to safeguard auxiliary power systems, On-Board Chargers (OBC), and secondary distribution circuits within Power Distribution Units (PDU).

Developed to meet the rigorous demands of the automotive industry, the EV315 series excels in environments subject to high-frequency vibrations, mechanical shocks, and thermal cycling. The high-speed response characteristic provides low let-through energy (I²t), ensuring that sensitive power electronics and semiconductor components are protected during fault conditions. The "3EN" bolt-on terminal design facilitates a secure, high-torque industrial connection, minimizing contact resistance and enhancing long-term operational stability.
