Envelope is 145 mm wide by 210 mm high by 202 mm deep, and the mounting surface can be vertical with ±90° rotation or ±22.5° tilt forward/back — useful when squeezing it into a drive cabinet corner where the busbars run overhead. ## Power and control wiring — what the terminals accept Main power terminals take stranded copper from 70 mm² up to 240 mm² — that's a heavy cable range suited for motor feeds up to perhaps 200+ A depending on duty, and the lug hole is sized for the full cross-section. ## Switching rates and duty-cycle reality Maximum switching frequency depends on the load category: AC-1 (resistive) allows 750 operations/hour, AC-3 (squirrel-cage motor start/run) caps at 500/h, and AC-4 (plugging/inching) drops to 130/h — the arc energy in reversing duty burns the contacts faster, so the controller logic must enforce a minimum off-time between reversals. The AC-3e (enhanced) rating also permits 500 cycles/hour, matching the standard AC-3 figure — no derating for the improved arc-chamber design. ## Coil specs and auxiliary switching Coil voltage is 240–277 V AC, with a pickup threshold of 0.8× rated and a dropout of 0.9× — so on a 240 V line the coil pulls in reliably down to about 192 V, but drops out if the supply sags to 216 V, which matters for brownout ride-through. ## Lifecycle and sourcing — active production, quoted per BOM Sourced through authorized industrial distribution channels; volume pricing and lead time confirmed at RFQ against your BOM quantity. No second-source cross-reference is documented — this is the Siemens SIRIUS part number, not a multi-brand equivalent.","metaTitle":"Siemens 3RT1064-6AU36 SIRIUS Power Contactor, S10 Size","metaDescription":"Siemens 3RT1064-6AU36 SIRIUS power contactor, S10 size, screw-type coil terminals, 240-277 V coil.
