The supplied contactor is a 3RT2018-2BB41, paired with link module 3RA2911-2AA00, so the assembly arrives as a matched set for motor starting duty. Mounts vertically only, with the following clearance requirements: 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards, and 0 mm backwards. The 45 mm width and 155 mm depth fit standard S00 feeder spacing on 60 mm busbar systems — no DIN rail adapter needed. Main circuit connections use spring-loaded terminals, which reduce wiring time compared to screw clamps — no torque driver needed for the power connections. The 24 V DC coil is standard for PLC-driven panels; confirm the control transformer rating for inrush at pickup. Operating temperature range is -20 to +60 °C with temperature compensation active across the same band. Storage and transport limits extend to -50 to +80 °C. The substance prohibitance date of 10/01/2009 aligns with RoHS compliance — no additional documentation request needed for EU markets.","metaTitle":"Siemens 3RA2110-4AH18-1BB4 SIRIUS Motor Starter, 16 A AC-3","metaDescription":"Siemens 3RA2110-4AH18-1BB4 SIRIUS direct-on-line starter, size S00, 16 A at 400 V AC-3, Class 10, for 60 mm busbars.
