Product details

Rated 22 kW at AC-2 duty at 400 V and 41 A at AC-4 at 400 V, it handles both standard motor starting (AC-2) and high-stress reversing or inching (AC-4) without derating the contactor size. The coil draws 10 A at 24 V rated value and 6 A at 230 V rated value, with a rated frequency of 50 Hz.

Width of 55 mm, height 112 mm, depth 164 mm; side-by-side mounting permitted, so multiple contactors pack tightly on the rail without derating. Main circuit terminals are screw-type, accepting solid 2x (0.25 … 2.5 mm²) and stranded 2x (0.75 … 25 mm²).

Current-production part — no obsolescence notice on record. Degree of pollution 3, IP20 on the front (finger-safe behind the panel door), IP00 at the terminals (inside the enclosure).

Frequently asked questions

What is the replacement for Siemens 3RT1036-3AF04?

No official replacement has been issued — the part remains active. For a functional cross-reference, the 3RT1044-1FB46 is a higher-rated sibling in the same SIRIUS family, but verify coil voltage and terminal style against your BOM.

What is 3RT1036-3AF04's listed depth?

The depth is 164 mm, with a width of 55 mm and height of 112 mm.

What is the difference between 3RT1036 and 3RT2036?

The 3RT1036 is a size S2 contactor (55 mm wide) in the SIRIUS family; the 3RT2036 is a larger frame size with higher current ratings and wider dimensions. For a direct fit comparison, check the AC-3/AC-4 ratings and terminal capacity against your load.
