It also handles 30 kW at 500 V and 11.4 kW at 690 V, giving flexibility across supply voltages common in European and export panels. The AC-3 rating at 400 V is 30 kW, covering standard squirrel-cage motors. ## Mechanical and Electrical Fit Dimensions are 112 mm height, 55 mm width, and 115 mm depth. The 55 mm width is the S2 standard — it occupies three 18 mm modular positions on the DIN rail, so check your enclosure fill factor. Side-by-side mounting is permitted, which saves rail space in multi-contactor groups. Solid wire capacity is 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), max 2x (0.75…4 mm²). Stranded accepts 2x (0.75…25 mm²), and solid or stranded goes up to 2x (0.75…16 mm²). That covers most panel wiring from control circuits up to motor feeders. The contactor is rated for 50/60 Hz operation with a voltage tolerance of 0.8…1.1 at 50 Hz and 0.85…1.1 at 60 Hz. Mechanical endurance is typical 10,000,000 operations, with maximum switching rates varying by duty: AC-1 at 1000 1/h, AC-3 at 800 1/h, AC-4 at 300 1/h.","metaTitle":"Siemens SIRIUS 3RT1036-1AH20-1AA0 Power Contactor, S2, 22kW","metaDescription":"Siemens SIRIUS 3RT1036-1AH20-1AA0 power contactor, size S2, 22 kW at AC-2 400V, 30 kW at 500V, 11.4 kW at 690V.
