Product details

It's rated for 22 kW at AC-2 duty on 400 V, and can handle 30 kW at 500 V or 11.4 kW at 690 V, so it covers a solid range of three-phase induction motors across common European and North American supply voltages. At 55 mm wide, it fits a standard panel slot without crowding adjacent devices. It's rated for both 50 Hz and 60 Hz supply, with an operating factor of 0.8 to 1.1 at either frequency.

If your line has a motor starting under load or reversing frequently, AC-2 is the duty class you need, and this contactor delivers it. The auxiliary contact block handles 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, so it can drive smaller relays or PLC inputs directly without an interposing relay in most panels.

Wiring and integration notes

Screw terminals on the main circuit accept 2x (0.75 to 25 mm²) stranded, or 2x (0.5 to 4 mm²) solid. The auxiliary terminals take 2x (0.75 to 16 mm²) solid or stranded. That covers most panel wiring from control to power feeds without needing adapters.

Frequently asked questions

What wire sizes does the 3RT1036-1AK64-3MA0 accept?

The main circuit screw terminals accept 2x (0.75 to 25 mm²) stranded wire, or 2x (0.5 to 4 mm²) solid wire. The auxiliary terminals accept 2x (0.75 to 16 mm²) solid or stranded.
