Ferraz Shawmut - Mersen A2D30-R Class RK1 / Time-Delay Amp-Trap 2000 SmartSpot A2D-R Fuse - 30amp. Rated 250 volts AC / DC

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 older 250V Class H, K or RK5 fuses already installed in the field. Features: 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 - 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
