Mersen Amp-Trap 2000 SmartSpot Series – For Type 2:

Amp-Trap 2000® SmartSpot AJT fuses now provide a 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.


  • 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
