HSJ225

Series: HSJ - Class J - High-Speed Fuse HSJ - Class J - High-Speed 600VAC 500VDC 225A Blade Amp-Trap® The High Speed Class J (HSJ) combines the low I2t of a semiconductor fuse and the branch-circuit performance of a Class J UL Listed fuse into a single design. The HSJ can provide both branch circuit protection per NEC requirements, as well as very low I2t for protection of power semiconductors such as Diodes, SCRs, GTOs and SSRs.
