The SIBA 2078432.1000 Ultra Rapid fuse (aR) is a high-speed DC protection device rated for up to 1000 V and 1000 A, with a breaking capacity of 100 kA and a Sz 3 size. This current-limiting fuse delivers rapid fault interruption to minimize energy transfer and protect downstream power electronics in demanding DC systems. Typically used in battery energy storage systems (BESS) and other high-voltage DC applications, SIBA Ultra Rapid fuses provide fast, reliable protection against short circuits and overloads.
