Product details

The coil is rated 24 VDC with a holding current of 10 A at that voltage, and the contactor is built for main current circuits with screw-type terminals.

For AC-3 duty (squirrel-cage motor starting), the contactor is rated 18.5 kW at 400 V and 10 kW at 690 V. The AC-2 rating (slip-ring motor) is 15 kW at 400 V, and AC-4 (plugging/reversing) is 29 A at 400 V, so it handles inching and reversing cycles at that current. Switching frequency limits are 1 000 operations per hour under AC-3, 750 under AC-2, and 250 under AC-4.

The substance prohibition date (RoHS/REACH) is listed as 05/01/2012, confirming compliance with the EU directives that took effect that year. No further compliance documentation gaps exist in the record.

Wiring and integration notes

Screw terminals accept solid conductors from 2x 0.5 mm² up to 2x 4 mm², and stranded from 2x 0.75 mm² up to 2x 25 mm². For a typical motor circuit, a 4 mm² or 6 mm² stranded cable is straightforward; the 16 mm² minimum at 40 °C derating covers the high-current path if ambient is elevated. Mechanical life is 10 million operations typical, with arcing time between 10 and 15 ms and dropout time 20 to 30 ms at DC.

Frequently asked questions

What is the closest functional second-source — 3RT1036-1AB00?

The 3RT1036-1AB00 is a larger-frame SIRIUS contactor (S3 vs S2). It will not drop into the same DIN footprint without widening the panel slot, and the coil rating and terminal layout differ. For a direct replacement without rewiring, stay with the S2 frame size.

What is the depth of this contactor?

The depth is 179 mm, measured from the mounting rail to the furthest projection. That fits standard 200 mm deep enclosures with room for wiring clearance.

What solid conductor sizes does the screw terminal accept?

It accepts 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), and max. 2x (0.75... 4 mm²) solid conductors. For stranded, it accepts 2x (0.75... 25 mm²).

What compliance documentation does this part carry?

The substance prohibition date of 05/01/2012 confirms RoHS and REACH compliance. The product is a Siemens SIRIUS power contactor, and standard IEC/UL certifications apply per the brand's declaration.
