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 I 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 I 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 exceHent
protection for all your applications.
Features/Benefits
~
Solid State SmartSpot Indicator
Time delay for motor starting and transformer inrush
~ 300kA interrupting rating -self-certified,
UL witnessed tests
~ Extremely current limiting for low peak leHhru current
~ Most current limiting UL class fuse
~ Small footprint requires less mounting space and
all ows smaller, more economical fuse blocks
~ Easy 2-to-1 selectivity for prevention of nuisance
shutdowns
~ Unique Class J dimensions prevent rep lacement errors
~ High-visibility orange label gives instant recognition
~ Metal-embossed date and catalog number for
traceability and lasting identification
~ Fiberglass body provides dimensional stability in harsh
industrial settings
~ High-grade silica filler ensures fast arc quenching
~ Optional El Indicator/Switch mount for AJT70 to
600 open fuse indication
