Ferraz Shawmut - Mersen HSJ80 600V 80A CLASS J HS FU

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. Features: Optimized over-load capability for withstanding elevated levels of current during electronic motor controller starts; Low I2t (low thermal energy); Excellent cycling ability for frequent starts/stops without nuisance opening - Applications: Branch circuits; Control panels; Electronic motor controllers; Phase controllers; Drives; Soft-starters; Solid state relays - Approvals & Standards: UL listed to standard 248-8 File E2137; CSA certified to standard C22.2 no. 248.8; DC listed to UL 248
