SMARTSPOT  WITH MAXIMUM CIRCUIT PROTECTION

A2D & A6D

TIME DELAY / CLASS RK1

Amp-trap 2000 SmartSpot A2D, A6D fuses now provide a visual open fuse indicator. With advanced material technology added to the existing product line the A2D, A6D fuses provide IEC Type "2" (No Damage) protection to main, feeder, and branch circuits, for all types of loads.

 A2D, A6D's time delay characteristics for handling harmless in-rush currents, its current limiting ability and wide range of ratings (from 1 to 600 Amperes), give excellent protection for all your applications.

Features/Benefits:

  • Solid State SmartSpot Indicator

  • Time delay for motor starting and transformer inrush currents without nuisance opening

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

  • Extremely Current Limiting for low peak let-thru current

  • 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 recognition

  • Reduced inventory by taking the place of RK5, K, and H fuses

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

  • Fiberglass body provides dimensional stability in harsh industrial settings

  • Brass end-caps (blade-style) for cooler operation and superior performance
