SMARTSPOT INDICATOR AMP-TRAP 2000®

AJT

TIME DELAY / CLASS J

HIGHLIGHTS:

➤ Smart Spot Indicator

➤ Time Delay

➤ Highly Current Limiting

➤ DC Ratings

➤ Optional Mechanical

Indicator

(70 to 600A fuses)

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 harm-

less 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.
