What ships in the carton — no holes in the kit
The 3RA2110-1HD15-1BB4: The starter ships as a complete assembly: the supplied contactor is a 3RT2015-1BB41 and the link module is a 3RA1921-1DA00. That means the thermal overload relay, contactor, and interconnecting wiring are pre-configured — no separate sourcing of the contactor or bus link.
Snap-on busbar mounting — panel integration
Designed for snapping onto 60 mm busbar systems, the starter mounts vertically and occupies a 45 mm width footprint. The overall dimensions are 45 mm wide × 155 mm deep × 203 mm high, with clearance requirements of 50 mm upwards, 20 mm forwards, 10 mm downwards, and 20 mm at the side — no clearance needed at the back. This fits standard S00-size feeder layouts in motor control centres.
Active production — sourcing posture
Listed as current production (lifecycle stage: current). The 3RA2110-1HD15-1BB4 is a standard SIRIUS catalogue item, so lead times are typically aligned with Siemens' production schedule.
