Amp-Trap 2000® AJT fuses provide non-indication as well as a SmartSpot®

visual open fuse indicator. With advanced material technology 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 are ideal for handling typical motor and transformer inrush

currents, while also providing superior current-limiting ability.

FEATURES/BENEFITS:

• Non-indicating or solid state SmartSpot visual open fuse indicator

• Time-delay for motor starting and transformer inrush

• 300kA interrupting rating - self-certified, UL witnessed tests

• Extremely current-limiting for low peak let-thru current

• Non-indicating fuses suitable for use in NEC Class I Division 2 hazardous

locations1

• Recommended for Arc Flash energy reduction

• Small footprint requires less mounting space and allows smaller,

more economical fuse blocks

• Easy 2-to-1 selectivity for prevention of nuisance shutdowns

• Unique Class J dimensions prevent replacement errors

• High-visibility orange label gives instant brand recognition

• Metal-embossed date and catalog number for traceability and

lasting identification

• Fiberglass body provides dimensional stability in harsh environments

• High-grade silica filler ensures fast arc quenching

• Optional EI open fuse indicator/switch mount for AJT70 to 600

Mersen highly recommends installation in Class I Division 2 certified sealed enclosure.
