The 110 V 50 Hz coil draws 10 A at 24 V on the auxiliary side, with a full auxiliary contact set of 1 NO + 1 NO/NC (18...1 configuration). Screw-type terminals on the magnet coil and main contacts accept 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid or stranded wire. ## What the 52 A AC-3 Rating Means for Your BOM Line The headline 52 A at 480 V AC-3 is the contactor's motor-switching current — the value that determines whether it can handle a specific motor's locked-rotor and breakaway load. For resistive loads (AC-1), the maximum switching frequency is 1,000 operations per hour; for AC-3 it's 800/h, and for the more demanding AC-4 (plugging, inching) it drops to 250/h. The auxiliary contact ratings span 10 A at 24 V down to 0.3 A at 220 V — enough for PLC inputs or relay coils in the control circuit. Mounting position is standing on a horizontal mounting surface.","metaTitle":"Siemens 3RT2036-1AF00-1AA0 SIRIUS Power Contactor, 52 A AC-3","metaDescription":"Siemens SIRIUS 3RT2036-1AF00-1AA0 power contactor, size S2.
