The auxiliary switch is factory-integrated, saving a separate add-on order for basic status feedback. That helps when you're shoehorning this into a crowded sub-panel and the DIN rail isn't perfectly level. The coil connection uses screw-type terminals — no spring-cage surprises for the panel builder. Main circuit wiring accepts solid conductors from 2.5 to 16 mm², or stranded from 6 to 70 mm². Auxiliary contacts take 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). That covers most motor-circuit wiring up to the S3 current class without needing adapter lugs. ## Clearance and thermal These are the numbers to hand to the panel designer so the contactor doesn't cook its neighbors or cause arc flash tracking. ## Switching rates and arc timing Maximum switching rates: 900 cycles/hour at AC-1 (resistive), 850 at AC-3 (standard motor start), 350 at AC-2 (slip-ring motors), and 250 at AC-4 (plugging/reversing). Arc duration is 10 to 21 ms at AC, and arcing time is 10 to 20 ms — both tight enough to avoid nuisance upstream breaker coordination in most industrial panels. Lifecycle stage is current.","metaTitle":"Siemens 3RT2046-1AK60-0UA0 SIRIUS Power Contactor, S3, 70mm","metaDescription":"Siemens SIRIUS 3RT2046-1AK60-0UA0 power contactor, size S3, 70mm width, screw terminals, auxiliary switch included.
