A2D-R - Reducer Fuses - 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.

Key features & benefits
Replaces traditional temporary-use only Fuse Reducer accessories
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
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 lower-rated Class RK1
fuses and associated Fuse Reducer accessories
Metal-embossed date and catalog number for easier traceability
and lasting identification
Fiberglass body provides dimensional stability in harsh industrial
settings
