S10 frame, screw-fixed — panel layout constraints
The 3RT1064-6AU36 is a SIRIUS S10-size power contactor, fastened by screw fixing through an 11 mm hole — no DIN-rail clip on this variant, so the panel backplate needs drilled and tapped mounts. 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.
