It switches AC-3 duty up to 690 V, which covers the vast majority of three-phase induction motors in industrial panels. The screw-type terminals on the main circuit accept up to 4 mm² conductors, and the coil draws 0.24 A at 50 Hz, 0.25 A at 60 Hz — a standard 24 VAC/DC coil that any 24 V control transformer can drive. At 45 mm wide and 73 mm deep, it takes up one standard 45 mm slot on the rail — same footprint as any S00 contactor. The motor power ratings are given at 60 °C ambient — a realistic panel temperature. At 400 V, it's rated 13 kW; at 230 V, 7.5 kW; at 690 V, 22 kW. These are AC-3 (squirrel-cage motor switching) values, which is the duty cycle that matters for most conveyor, pump, and fan loads. The AC-1 resistive rating (heater or lighting loads) is higher, but for motor duty, the AC-3 figure governs. The contactor is rated for 30 million mechanical operations typical, so it outlasts the machine in most applications. Pollution degree 3 (industrial environment, conductive pollution). RoHS compliance date listed as 05/01/2012 — it's been RoHS-compliant for over a decade. The insulation voltage is rated 690 V, matching the maximum switching voltage.","metaTitle":"Siemens 3RT6018-1AK61 SIRIUS Contactor, S00, 13 kW at 400 V","metaDescription":"Siemens 3RT6018-1AK61 SIRIUS power contactor, size S00, 13 kW at 400 V 60°C, screw terminals, 45 mm wide, active production.
