16 A AC-3 at 400 V — S00 direct-on-line starter for busbar mounting
The Siemens 3RA2110-4AH18-1BB4 is a SIRIUS direct-on-line starter in size S00, designed to snap onto 60 mm busbar systems — the mounting method is built into the housing, not an add-on bracket. 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.
