The High Speed J (HSJ) fuse combines the low I2t of a semiconductor fuse and the branch circuit performance of a Class J UL listed fuse. This fuse was designed for the starting characteristics of solid state motor controllers. The HSJ can provide branch circuit protection per NEC requirements, as well as very low I 2t for protection of power semiconductors such as Diodes, SCR's, GTO's and SSR's.
