Product details

The contactor accepts solid or stranded conductors from 1 to 10 mm² on the main circuit, and the auxiliary wiring can take 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).

Dimensions and Clearances

At 85 mm high, 45 mm wide, and 141 mm deep, this contactor fits the standard S0 footprint. That 6 mm side gap is the tightest constraint — adjacent devices on the rail need that spacing for heat dissipation and arc containment.

Switching Performance and Mechanical Life

Rated for 1,000 operating cycles per hour under AC-1, AC-2, AC-3, and AC-3e duty, dropping to 300 cycles per hour under the heavier AC-4 category. Arcing time is a tight 10 ms window, and the make/break times at AC sit between 4 and 16 ms.

Frequently asked questions

Where can I buy 3RT2024-1AK64-3MA0 and get current pricing?

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

What is the depth of this contactor?

The depth is 141 mm, with a width of 45 mm and height of 85 mm. Side clearance required is 6 mm; other clearances are 10 mm.

What wire sizes does the 3RT2024-1AK64-3MA0 accept?

The main circuit accepts solid or stranded conductors from 1 to 10 mm². Auxiliary terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).

Will 3RT2024-1AK64-3MA0 drop into a panel specified for 3RT2024-1AL20-ZX95?

Both are Size S0 contactors sharing the same mounting rail and dimensional envelope, so the mechanical fit is identical. The difference is in the coil termination: the -1AK64-3MA0 uses screw-type terminals, while the -1AL20-ZX95 uses a different termination style. If the panel wiring was prepared for cage-clamp or spring-loaded connections, the screw terminal variant will require different wiring preparation.
