Its headline motor rating is 22 kW at 500 V under AC-3 duty (cites:), which means it handles the inrush and running current of a standard three-phase induction motor up to that power — the rating that governs real-world motor switching, not the higher AC-1 resistive rating. For heavy-duty jogging or plugging (AC-4), it is rated 35 A at 400 V (cites:), so it can withstand the higher electrical wear of frequent reversals without premature contact degradation.
The 55 mm width (cites:) and 112 mm height (cites:) fit standard panel layouts; depth is 115 mm (cites:). Terminals are screw-type for the main circuit (cites:), accepting stranded conductors up to 2x 25 mm² (cites:) and solid up to 2x 4 mm² (cites:). IP20 on the front (cites:) means finger-safe in the enclosure; the terminal area is IP00 (cites:), so live parts are exposed outside the panel — plan for a proper enclosure door.
Sourcing Posture
No last-time-buy or surplus dependency applies. For a panel originally specified around the 3RT1036-1AB00 (a higher-rated sibling), this unit will not drop in without rewiring: the 3RT1036 is a larger frame with different terminal spacing and current capacity. Stick with the code on your schematic.
