250V 5A RK1 TD FUSE

250V 5A RK1 TD FUSE

Item #: A2D5R

Supplier Part #: A2D5R
Brand: Mersen

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.

Solid state SmartSpot visual blown fuse indicator; All general-purpose circuits; 600VAC & 600VDC dual rated; Reduced inventory by taking the place of class RK5, K, and H fuses; Fiberglass body provides dimensional stability in harsh industrial settings; Transformers; CSA certified to standard C22.2 No. 248.12; 300kA interrupting rating – self-certified, UL witnessed tests; Easy 2-to-1 selectivity for prevention of nuisance shut downs and “black outs”; DC listed to UL standard 248; UL listed to standard 248-12 File E2137; Disconnects; Extremely current-limiting for low peak let-thru current; Time-delay for motor starting and transformer inrush currents without nuisance opening; Branch circuit protection; High-visibility orange label gives instant brand recognition; Rejection-style design prevents replacement errors (when used with recommended fuse blocks); Motors; Control panels; Metal-embossed date and catalog number for easier traceability and lasting identification; Recommended for Arc Flash energy reduction; Safety switches
