Product details

Rated for AC-3 duty at 750 operating cycles per hour maximum, this contactor handles the frequent start-stop demands of conveyor and pump applications. For resistive loads (AC-1), it can cycle up to 1000 times per hour. The coil draws 0.25 A at 50 Hz and 0.28 A at 60 Hz, a narrow spread that keeps the control transformer sizing consistent regardless of line frequency.

Wire range accepts solid or stranded conductors from 1 to 10 mm² for the main circuit, and 2x (0.5 to 2.5 mm²) for finer control wiring. The spring-type terminals on the coil eliminate the risk of loose screw connections under vibration — relevant for machines with frequent cycling.

Frequently asked questions

What are the key ratings for 3RT2026-2AK64-3MA0?

It is an S0-size power contactor rated for AC-3 duty at 750 operating cycles per hour maximum, with spring-type terminals, 45 mm width, and a 144 mm depth. The coil draws 0.25 A at 50 Hz and 0.28 A at 60 Hz.

Where can I buy 3RT2026-2AK64-3MA0?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm offer.

How does 3RT2026-2AK64-3MA0 compare to 3RT2015-2AP02?

The 3RT2015-2AP02 is a smaller frame size (S00 vs S0) with a lower current rating and screw terminals. The 3RT2026-2AK64-3MA0 offers higher switching capacity and spring-type coil terminals, but both share the same DIN rail mounting pattern and SIRIUS accessory ecosystem. Panel re-wiring is required when swapping between the two due to different terminal arrangements and frame dimensions.
