Description:

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. 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. Application Motors Safety Switches, Transformers, Disconnects, Control Panels, All General-purpose Circuits. Mersen (also known as Ferraz Shawmut and Gould Fuses).
