The 3RT2046-1AK60-0UA0: The S3 frame measures 70 mm wide by 140 mm high by 152 mm deep, which is the footprint you need to check against your existing panel layout and busbar spacing. 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.
