Description
250A 600V J HIGH SPEED
Class J Very Fast Acting High Speed Fuse
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.
- 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
