SIRIUS S00 direct starter — 16 A AC-3, snaps onto 60 mm busbars
The Siemens 3RA2110-4AD18-1BB4 is a SIRIUS direct-on-line starter in size S00, combining a contactor and overload relay in one unit for snapping onto 60 mm busbar systems. The 24 V DC coil keeps control voltage low for PLC-driven panels; the supplied contactor is a 3RT2018-1BB41 and the link module is 3RA1921-1DA00, so the assembly arrives as a matched set ready to wire.
Motor current across voltage taps — what the ratings mean
At 400 V AC-3 the starter handles 16 A, which translates to 7.5 kW — the rating that governs most European 400 V motor circuits. At 480 V it carries 14 A, at 600 V it carries 11 A. Horsepower equivalents span 1 hp at 110/120 V up to 10 hp at 460/480 V. The maximum operating voltage is 690 V AC-3. For high-inertia loads (fans, flywheels) a Class 20 or 30 starter would be needed; this unit is sized for typical pump, compressor, and conveyor motors.
Mounting and panel fit — S00 on 60 mm busbars
The starter snaps directly onto 60 mm busbar systems — no DIN rail adapter needed. Dimensions are 45 mm wide, 203 mm high, 155 mm deep. Mounting position is vertical. Clearance requirements: 50 mm above, 20 mm in front, 20 mm to the side, 10 mm below, 0 mm behind. Main circuit connections are screw-type terminals — torque specs follow the S00 terminal chart. Ambient operating range is -20 to +60 °C; storage and transport range is -50 to +80 °C.
Lifecycle and sourcing — active, quoted to order
RoHS compliance date is 10/01/2009. The starter carries the SIRIUS brand and is designed for global IEC and UL/CSA motor circuits up to 690 V.
