Mersen/Ferraz Shawmut A2D45R Amp-Trap 2000 Class RK1 Time-Delay Fuse, 45A 250V - Lot of 18

This lot includes eighteen (18) high-performance A2D45R (45 Amp) Class RK1 fuses manufactured by Mersen (formerly Ferraz Shawmut). As part of the Amp-Trap 2000® series, these fuses are engineered to provide "No Damage" IEC Type 2 protection for both motor and non-motor circuits, ensuring critical industrial components are shielded during faults.  Superior Protection: Designed with a dual-element, time-delay construction that effectively handles high inrush currents from motor starting and transformer applications without nuisance tripping.  Highly Current-Limiting: These fuses significantly reduce peak let-through current, providing superior protection against the destructive effects of short circuits compared to standard Class RK5 fuses.  Rejection-Style Design: Features a rejection-style cap to prevent the installation of lower-rated fuses into Class RK1 fuse clips.  Industrial Durability: Built with a glass melamine body for exceptional dimensional stability and high-grade silica filler for rapid arc quenching.  Technical Specifications (Per Fuse):Amperage Rating: 45 Amps.  Voltage Rating: 250 VAC / 250 VDC.  Interrupting Rating: 200kA at 250VAC.  Standards: UL Listed to Standard 248-12 and CSA Certified.  Applications: Ideal for motor circuits, transformers, service entrance equipment, feeder circuits, and general-purpose branch circuit protection.
