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 EC 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.
