HSJ

HIGH SPEED/CLASS J
Protect your wiring and power semiconductors with a single fuse.
The new High Speed J (HSJ) 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 I2t for protection of power semiconductors
such as Diodes, SCR’s, GTO’s and SSR’s.
Features/Benefits
➤ 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

HIGHLIGHTS:

Applications:
