Sinofuse EV315-L-3EC15A Electric Vehicle Fuse, 15A 500V DC, High-Speed Bolt-on - Pack of 10

The Sinofuse EV315-L-3EC15A is a high-performance, high-speed DC fuse engineered for the protection of critical auxiliary circuits in Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) systems. Rated for 15A at 500V DC, this fuse is specifically designed to safeguard components such as On-Board Chargers (OBC), DC/DC converters, and Power Distribution Units (PDU).

This component is manufactured to strict automotive quality standards, including ISO 8820 and JASO D622, ensuring exceptional reliability under harsh vehicle operating conditions. It features high-speed interruption capabilities that limit let-through energy (I²t), thereby protecting sensitive semiconductor devices from thermal damage during short-circuit or overcurrent events. The 3EC bolt-on terminal design ensures a high-integrity mechanical and electrical connection that is resistant to the intense vibrations and thermal cycling typical in automotive applications.
