Main power terminals are screw-type, accepting 2x (0.75 to 25 mm²) stranded or 2x (0.25 to 2.5 mm²) solid wire. The control circuit terminals handle 2x (0.75 to 16 mm²) solid or stranded. That's enough cross-section for the full AC-1 and AC-3 current ratings without needing to parallel conductors. The minimum solid wire size of 0.25 mm² is fine for signal-level control wiring, and the 25 mm² stranded max covers the main power feed for the 22 kW motor circuit. ## Coil and auxiliary ratings The coil operates at 50 Hz and pulls 27 VA at 50 Hz rated value. Auxiliary contact ratings are given for several control voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. These cover most common PLC output and relay interface voltages.","metaTitle":"Siemens 3RT1036-3AX00-0AA3 SIRIUS Power Contactor, 22 kW AC-","metaDescription":"Siemens SIRIUS 3RT1036-3AX00-0AA3 power contactor, Size S2, 22 kW at AC-2 400 V.
