A6D-R - Class RK1 - Time-Delay

Approvals & Standards
UL listed to standard 248-12 File E2137
DC listed to UL standard 248
CSA certified to standard C22.2 No. 248.12

Amp-Trap 2000® time-delay A6D-R fuses provide IEC Type 2 "no damage" protection to existing mains, feeders, and branch circuits serving motor and non-motor loads. A6D-R fuses will open fast enough under extreme fault conditions for maximum short circuit protection to prevent damage to motor starters, switches, and other circuit components, yet also provide the time-delay needed for motor in-rush currents. A6D-R fuses can be used to replace older 600V Class H, K or RK5 fuses already installed in the field.

Key features & benefits

  • Non-indicating or Solid state SmartSpot visual blown fuse indicator

  • 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

  • Reduced inventory by taking the place of class 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

Applications

  • Motors

  • Safety switches

  • Transformers

  • Branch circuit protection

  • Disconnects

  • Control panels

  • All general-purpose circuits
