SIRIUS reversing starter, size S00 — active production, 16 A AC-3
The Siemens 3RA2210-4AS18-2BB4 is a SIRIUS reversing starter in size S00, designed for snapping onto 60 mm busbar systems — a common panel layout for motor control centres. Horsepower ratings span 1 hp at 110/120 V up to 10 hp at 460/480 V.
Mounting and panel clearances — 60 mm busbar snap-on
Fastens by snapping onto 60 mm busbar systems; mounting position is vertical. Dimensions: 230 mm height, 90 mm width, 155 mm depth. Required clearances for ventilation and arc flash: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, 0 mm backwards. The main current circuit uses spring-loaded terminals — no screw torque verification needed, which speeds panel wiring and reduces inspection points.
Rated operating conditions and temperature range
Operates in ambient temperatures from -20 °C to +60 °C; storage and transport range is -50 °C to +80 °C. Temperature compensation is active across the full operating range. Coil rated 24 V DC (24... 24 V). The supplied contactor is 3RT2018-2BB42 and the link module is 3RA2911-2AA00 — both are current-production SIRIUS components. Substance prohibitance date 10/01/2009 indicates RoHS compliance; no PROFIsafe or PROFINET IO protocol support on this variant.
