FAST ACTING / CLA:
FOR EXCELLENT CURRENT LIMITING
PROTECTION
A4J Class J fuses deliver excellent current-limiting
protection to a wide variety of applications. Their
unique dimensions prevent the substitution of
other fuses with lower voltage ratings, interrupting
ratings, or current-limiting capability.
Features/Benefits
-
High current limitation for low peak let-thru current
Unique dimensions prevent replacement by other fuse
classes
'• Fiberglass body provides dimensional stability in
harsh industrial environments
> Easy-to-read imprint label for quick recognition
and replacement

SMARTSPOT INDICATOR AMP-TRAP 2000'

AJT
TIME DELAY / CLASS J
SMARTSPOT™ WITH MAXIMUM CIRCUIT
PROTECTION
Amp-trap 2000® SmartSpot™ AJT fuses now
provide a visual open fuse indicator. With advanced
material technology added to the existing product
line the AJT fuse provides IEC Type "2" (No Damage)
protection to main, feeder, and branch circuits, for all
types of loads — yet, they require only half the
mounting space needed for 600VAC Class RK fuses.
AJT's time delay characteristics for handling harmless in-rush currents, its current limiting ability (the
most current limiting UL fuse class!), and wide range
of ratings (from 1 to 600 Amperes) — give excellent
protection for all your applications.
