A2D-R - Class RK1 - Time-Delay

Amp-Trap 2000 time-delay A2D-R fuses provide IEC Type 2 "no damage" protection to existing mains, feeders, and branch circuits serving motor and non-motor loads. A2D-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. A2D-R fuses can be used to replace older 250V Class H, K or RK5 fuses already installed in the field.

• 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
