Product details

It is rated for AC-3 duty at 11 kW on both 500 V and 690 V supplies, and delivers 15.5 A in AC-4 at 400 V — the figure that governs reversing or inching applications where the contactor makes and breaks the load under full current. The coil is rated for 50 Hz operation.

The AC-3 rating of 11 kW at 690 V is the standard motor-switching figure for a contactor this size — it handles a 15 kW motor at 400 V (the common European line voltage) with headroom. For resistive loads (AC-1), the contactor is rated at 10 A (AC-12). The mechanical life of 10 million operations means the coil and armature will outlast the contacts in most cycling applications.

Side-by-side mounting is allowed with zero gap, saving panel width — the 65 mm wide body fits three across a standard 200 mm DIN rail section.

Frequently asked questions

Where can I buy 3RT1026-3AP06?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

What is the depth of 3RT1026-3AP06?

The depth is 91 mm, which is the dimension from the DIN rail mounting surface to the front of the contactor.

What wire sizes does the 3RT1026-3AP06 accept?

The screw terminals accept solid or stranded wire: 2x (0.25 to 2.5 mm²), 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), and up to 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), and 1x 8.

Will 3RT1026-3AP06 drop into a panel designed for 3RT1023-1AL20?

Both are S0 frame contactors with the same 65 mm width and DIN rail mounting, so the footprint and panel cutout are identical. The main difference is the coil voltage and contact configuration — verify the coil rating and auxiliary contact arrangement before swapping.
