The Amp-Trap 2000® SmartSpot® A2D-R fuses feature a visual open fuse indicator and provide IEC Type 2 No Damage protection to main, feeder, and branch circuits for all types of loads.

  • Time-delay characteristics for handling harmless in-rush currents, current-limiting ability and a wide range of ratings (from 1 to 600 A)

  • Time-delay for motor starting and transformer inrush currents without nuisance opening
  • 600VAC & 600VDC dual rated
  • 300kA interrupting rating - self-certified, UL witnessed tests
  • Extremely current-limiting for low peak let-thru current
  • Recommended for Arc Flash energy reduction
  • Easy 2-to-1 selectivity for prevention of nuisance shut downs and “black outs”
  • Rejection-style design prevents replacement errors (when used with recommended fuse blocks)
  • High-visibility orange label gives instant brand recognition

  • Metal-embossed date and catalog number for easier traceability and lasting identification
