AJT - Class J - Time-delay
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
- Non-indicating or solid state SmartSpot visual blown 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
 - Most current-limiting UL class fuse
 - 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 industrial settings
 - High-grade silica filler ensures fast arc quenching
 - Optional EI indicator/switch mount for AJT70 to 600 open fuse indication
