Reversing starter that snaps onto 60 mm busbars
The 3RA2210-1GS15-2BB4: It comes as a pre-assembled unit: the supplied 3RT2015-2BB42 contactor, 3RA2911-2AA00 link module, and 8US1251-5DS11 busbar adapter mount directly onto 60 mm busbar systems via the snap-on fastening method.
Spring terminals and clearance for panel planning
Main circuit connections use spring-loaded terminals — no screwdriver torque check, no loose lugs after a vibration cycle. The unit is 155 mm deep, 90 mm wide, 212 mm tall, and mounts vertically. Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, and 0 mm backwards — that zero backward clearance means the back of the housing can sit flush against the panel backplate. Operating temperature range is -20 to +60 °C, with temperature compensation built into the overload curve across that span. Storage and transport limits extend from -50 to +80 °C.
Motor power coverage across common line voltages
At 480 V the rated current is 4.8 A. The maximum AC-3 operating voltage is 690 V, and frequency is 50/60 Hz. The overload release is thermal bimetallic — no electronic adjustment, no auxiliary power needed for the trip curve. This keeps the assembly simple and field-reliable: if the bimetals heat up, the starter opens; when they cool, it resets.
Active production, sourced per RFQ
Substance prohibition date per RoHS is 10/01/2009 — the starter complies with the original RoHS directive. No REACH or UL certificate numbers are on the spec record; the buyer should request the Siemens declaration of conformity for their compliance file.
