ULTRASAFE modular
600 volt Fuse Holders for
Class J fuses introduce
a new level of safety and
ease for installing or
replacing Class J fuses.
5,42!3!&% HOLDERS
qualify as “finger safe” to
an IP20 grade of protection
under IEC standards. The
US3J accommodates 30A Class J or 22 x 58
mm French Ferrule* fuses. The US6J is for 60A
#LASS * FUSES 5,42!3!&% HOLDERS ARE
available in compact 1,2, or 3 pole units, with
or without blown-fuse indicators in each pole.
Multi-pole units can also be made up in the field
by using the multiple-pole Assembly Kits.
All units have provisions for locking in the open
position for safety during fuse changeouts or
equipment servicing. US3J and US6J holders
can be snap-mounted to 35 mm DIN rail and
they have a unique latch which will stay open
to allow repositioning of the holder in the future.
Ultrasafe body material is tough and durable
polyamide.

HIGH-SPEED FUSES
AMP-TRAP®
HIGH SPEED CLASS J FUSES
Advance protection for drives and soft starters
Protect your wiring and power semiconductors
with a single fuse.
The new High Speed J (HSJ)
combines the low I
2
t of a semiconductor fuse and
THE BRANCH CIRCUIT PERFORMANCE OF A #LASS * 5, 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
2
t for protection of
power semiconductors such as Diodes, SCR’s, GTO’s
and SSR’s
Features
Optimized over-load capability for withstanding
elevated levels of current during electronic motor
controller starts.

Prevent One Monster of a Problem With
Amp-Trap® High-Speed J Fuses
Most of today’s drives and soft-starters
don’t have room for the high-speed internal
fusing that protects their sensitive power
semiconductors. And while traditional branch
circuit protection meets NEC® requirements,
it leaves motor controllers vulnerable to costly
damage and downtime.
That’s why Fernaz Shawmut created the
Amp-Trap High-Speed J fuse. Specifically
designed to safeguard electronic motor
controllers, this monster of a fuse combines
the overload capacity and dimensions the
overload capacity and dimensions of a Class
J with the performance of a semiconductor
fuse.
The result is one fuse that provides two kinds
of protection — the branch circuit protection
required by the NEC and the high-speed
protection you need to prevent damage to
your motor controller’s sensitive internal
electronics.
