Product details

It is rated for 55 kW at 500 V and 25.4 kW at 690 V, making it suitable for medium-horsepower three-phase motors on 400 V to 690 V networks.

The 146 mm height and 70 mm width keep it within a standard enclosure depth.

The headline motor ratings are 55 kW at 500 V and 25.4 kW at 690 V — these are the AC-3 duty figures that govern switching of squirrel-cage motors during starting and running. For resistive loads (AC-1), the contactor can handle higher switching rates: up to 900 operations per hour. For the toughest duty, AC-4 (plugging, inching), the rate drops to 250 operations per hour. The auxiliary contacts are rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough for most PLC or relay control signals.

Frequently asked questions

What is the closest functional second-source?

The 3RT1036-1AB00 is a smaller size (S2) contactor from the same SIRIUS family. It will not drop into the same footprint without rewiring — the S3 frame has different mounting dimensions and terminal spacing. If you need a direct replacement without panel modifications, stick with the S3 frame size.

What is the depth of this contactor?

The depth is 139 mm.

What solid wire sizes does the terminal accept?

The screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and a maximum of 2x (0.75 to 4 mm²) solid conductors.

What compliance documentation is available?

The product is a Siemens SIRIUS contactor carrying CE marking for the European market. Specific RoHS, REACH, and UL documentation is typically included with the shipment or available on request from the manufacturer.
