HSJ

HIGH SPEED/CLASS J

PROTECT YOUR WIRING AND POWER
SEMICONDUCTORS WITH A SINGLE FUSE.

2

The new High Speed J (HSJ) combines the low I
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

t for protection of
power semiconductors such as Diodes, SCR’s, GTO’s and
SSR’s.
