At 55 mm wide, it fits a standard panel slot without crowding adjacent devices. It's rated for both 50 Hz and 60 Hz supply, with an operating factor of 0.8 to 1.1 at either frequency. If your line has a motor starting under load or reversing frequently, AC-2 is the duty class you need, and this contactor delivers it. The auxiliary contact block handles 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, so it can drive smaller relays or PLC inputs directly without an interposing relay in most panels. ## Wiring and integration notes Screw terminals on the main circuit accept 2x (0.75 to 25 mm²) stranded, or 2x (0.5 to 4 mm²) solid. The auxiliary terminals take 2x (0.75 to 16 mm²) solid or stranded. That covers most panel wiring from control to power feeds without needing adapters.","metaTitle":"Siemens 3RT1036-1AK64-3MA0 SIRIUS Power Contactor, Size S2,","metaDescription":"Siemens SIRIUS power contactor 3RT1036-1AK64-3MA0, Size S2, rated 22 kW at AC-2 400V, 30 kW at 500V.
