Sinofuse EV315-M-3E15A Electric Vehicle Fuse, 15A 500V DC, High-Speed Bolt-on

The Sinofuse EV315-M-3E15A is a high-performance bolt-on fuse specifically engineered for the overcurrent protection requirements of road vehicles, including Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). Rated at 15A and 500V DC, this fuse is designed to protect auxiliary circuits, power distribution units (PDU), and on-board chargers from short circuits and transient surges.

The "M-3E" designation indicates a bolt-on mounting structure, which provides superior mechanical stability and electrical contact reliability compared to standard ferrule types. This vibration-resistant design is critical for automotive applications where constant motion and thermal cycling are present. Built to comply with international automotive standards, it offers a high breaking capacity of 20kA and low I²t characteristics to ensure rapid isolation of faults, safeguarding sensitive power semiconductor components.
