SIRIUS S10 power contactor — panel fit and main conductor sizing
The 3RT1066-6AF36-ZX95: The main power terminals accept stranded conductors from 70 mm² up to 240 mm², so it pairs with large-gauge cable runs common on 200+ A motor circuits. The auxiliary contact block uses smaller terminals — solid or stranded wire from 0.5 mm² to 4 mm² — which is typical for control wiring in a 24 VDC or 110 VAC pilot circuit. Both the coil and auxiliary terminals are screw-type, so no special crimp tooling is needed beyond standard screwdrivers. Physical footprint is 202 mm deep by 145 mm wide by 210 mm high. Mounting is by screw fixing through an 11 mm diameter hole, with the contactor body rotatable ±90° on a vertical surface and tiltable ±22.5° front-to-back — useful when fitting into tight or angled panel sub-assemblies.
Coil voltage, auxiliary contact ratings, and switching duty
For a 24 VDC PLC input circuit, that 10 A rating is well above the typical 0.5 A fuse limit, so the auxiliary contacts will handle pilot duty without issue. Switching frequency varies by duty class: AC-1 (resistive) allows 750 operations per hour, AC-3 (motor starting) allows 500 per hour, AC-4 (plugging/inching) drops to 130 per hour. The AC-3e rating also shows 500 ops/h — this is the energy-efficient motor version of the same duty.
Environmental limits and sourcing posture
The contactor requires 10 mm clearance upwards, downwards, and at the sides, plus 20 mm forwards — these are minimum air gaps for arc flash and heat dissipation, not suggestions.
