Reversing starter, pre-assembled pair
The Siemens 3RA2210-0BA15-2BB4 is a SIRIUS reversing starter in size S00 — a factory-assembled pair of a 3RT2015-1BB42 contactor and a 3RA1921-1DA00 link module, with a thermal bimetallic overload relay and magnetic short-circuit release built into the same footprint.
Mounting and panel fit
Main circuit connections are screw-type terminals; the supplied link module bridges the contactor pair for reversing logic without external wiring.
Environmental and compliance
Operates from -20 to +60 °C ambient, stores from -50 to +80 °C — suitable for unheated enclosures in temperate climates. Rated for 50/60 Hz supply. The substance prohibitance date of 10/01/2009 aligns with RoHS compliance (EU RoHS took effect July 2006; this date is the manufacturer's declaration reference).
