The Eaton Bussmann EV30 is a DC-rated fuse for electric vehicle power circuits. It is rated for 300 A and supports a voltage range of 300–500 VDC, with a DC interrupt rating of 20 kA to quickly clear faults in high‑current EV applications. This EV30 device protects critical DC paths such as battery connections, motor drive circuits, and DC bus lines within electric vehicle architectures, helping prevent damage from overloads and short circuits.
