SIRIUS S00 reversing starter for 60 mm busbar panels
The Siemens 3RA2210-1CD15-2BB4 is a SIRIUS reversing starter in size S00, designed specifically for snapping onto 60 mm busbar systems — common in European-style motor control centers and panel builds where the busbar doubles as the mounting rail. The 24 V DC coil (rated value 24... 24 V) keeps the control circuit in the low-voltage safety range, common for PLC-driven panels where 24 VDC is the standard logic rail.
What the AC-3 rating means for motor sizing
At 400 V AC-3, the 2.5 A rating corresponds to roughly 1.5 hp (1.1 kW) motor full-load current — this starter is sized for small conveyors, pumps, or fan drives up to that power. The supplied contactor is a 3RT2015-1BB42, and the link module is 3RA1921-1DA00 — both matched to the S00 frame for coordinated thermal and magnetic protection. Operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C — adequate for most indoor panel environments, including unheated warehouses.
Snaps onto 60 mm busbar systems — no DIN rail needed. Mounting position is vertical only. The unit is 90 mm wide, 204 mm tall, 155 mm deep, with 50 mm clearance required above and 32 mm in front for wiring access. Main circuit connections use screw-type terminals — no special tooling needed, but torque to the Siemens specification for the S00 frame (typically 1.2–1.5 Nm for the power terminals). Side clearance is 10 mm; backwards clearance is zero — the unit can sit flush against the back panel or a busbar support.
