Low Voltage UL/CSA Fuses
Class RK1
A2D-R - Class RK1 - Time-Delay
Amp-Trap 2000 SmartSpot 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 obsolete 250V Class H, K or RK5 fuses already installed in the field.
FEATURES
- Solid-state SmartSpot indicator
- Time-delay for motor starting and transformer inrush currents without nuisance opening
- 300kA interrupting rating, self-certified (UL witnessed)
- 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 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
- High-grade silica filler ensures fast arc quenching
