Sinofuse EV315-3EN10A Electric Vehicle Fuse, 10A 500V DC, High-Speed Bolt-on - Pack of 10

The Sinofuse EV315-3EN10A is a precision high-speed DC fuse engineered for the demanding overcurrent protection requirements of Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) systems. With a 10A current rating and a 500V DC capacity, this component is specifically designed to protect lower-power auxiliary circuits, sensing lines, and delicate electronic modules within Power Distribution Units (PDU) and Battery Management Systems (BMS).

As part of the automotive-grade EV315 series, the EV315-3EN10A is manufactured to withstand the rigorous conditions of vehicular operation, including high-frequency vibration, mechanical shock, and wide temperature fluctuations. Its fast-acting clearing characteristics effectively minimize let-through energy (I²t) during fault events, shielding sensitive downstream components from damage. The "3EN" terminal style provides a secure bolt-on mounting interface, ensuring a vibration-resistant and low-resistance electrical connection essential for long-term automotive reliability.
