Product details

Its key motor rating is 22 kW at AC-2 duty at 400 V, which covers applications like slip-ring motors and moderate-duty starting. It also carries a 30 kW rating at 500 V.

The 55 mm width means it takes three standard DIN modules. Terminals are screw-type on the main circuit, accepting up to 2x 25 mm² stranded — wires up clean for a 22 kW motor feed. The auxiliary circuit handles 2x 2.5 mm² solid.

AC-3 maximum switching frequency is 800 cycles per hour; AC-4 (plugging/inching) drops to 300 1/h. The contactor is rated for 10 million mechanical operations typical, so it outlasts most panel builds in normal cycling.

Frequently asked questions

What is the closest functional alternative to the 3RT1036-3AN20?

The 3RT1044-1FB46 is a larger-frame SIRIUS contactor. It will not drop into the same panel footprint without rewiring — the 3RT1036 is Size S2 at 55 mm wide, while the 3RT1044 is a physically larger Size S3 unit with different terminal spacing and a higher current rating. Use the 3RT1036 for a direct fit.

What compliance documentation is available for this part?

As a current-production Siemens SIRIUS component, it is supplied with a CE declaration of conformity and UL/CSA certification. RoHS and REACH compliance declarations are available from Siemens documentation portals. The IP20 rating on the front and IP00 at the terminals are per IEC 60947.
