Sinofuse EV315-L-3EC30A Electric Vehicle Fuse, 30A 500V DC, High-Speed Bolt-on - Pack of 10

The Sinofuse EV315-L-3EC30A is a robust high-speed DC fuse engineered for the advanced overcurrent protection requirements of Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) power systems. With a 30A current rating and a 500V DC operating voltage, this component is specifically designed to protect mid-to-high power auxiliary circuits, Power Distribution Units (PDU), and On-Board Chargers (OBC).

Designed to comply with international automotive standards including ISO 8820 and JASO D622, the EV315-L-3EC30A offers exceptional reliability under conditions of severe vibration, mechanical shock, and cyclic thermal stress. Its fast-acting performance ensures low let-through energy (I²t) and rapid fault isolation, which is critical for safeguarding semiconductor switches and high-value DC electronics. The "3EC" bolt-on terminal configuration provides a high-torque, low-resistance connection, ensuring long-term operational stability in vehicular environments.
