The supplied contactor is 3RT2015-1FB41 and the link module is 3RA1921-1DA00, meaning the starter ships as a matched assembly with coordinated thermal and magnetic protection. Trip class 10 means it disconnects the motor within 10 seconds under locked-rotor conditions, meeting IEC 60947-4-1 requirements for standard motor starting applications. ## Control voltage and terminal wiring The coil is rated 24 V DC — a common control voltage in PLC-based panels, but verify your control transformer or power supply matches the DC polarity and voltage tolerance. Main current circuit termination uses screw-type terminals, rated for the 3.2 A AC-3 load at up to 690 V maximum. Dimensions are 45 mm wide by 155 mm deep by 203 mm high — the width fits a single 45 mm busbar pitch, so adjacent starters sit without side-to-side clearance issues. Operating temperature range is -20 to +60 °C, with storage and transport tolerance from -50 to +80 °C, so it handles unheated warehouses and trucking in cold climates.","metaTitle":"Siemens 3RA2110-1DD15-1FB4 SIRIUS Direct-on-Line Starter","metaDescription":"Siemens SIRIUS 3RA2110-1DD15-1FB4 direct-on-line starter, 3.2 A at 400 V AC-3, size S00, 24 V coil.
