The Siemens 3RA1110-0CA15-1BP4 is a nonreversing combination starter in the SIRIUS S00 frame, rated for 0.18-0.25 A with a 230 VDC control voltage. It integrates a motor starter protector (MSP) and a contactor in one DIN-rail or panel-mount unit, which simplifies wiring and reduces panel space compared to separate components. The 230 VDC coil means it is suited for DC control circuits common in battery-backed or safety-isolated panels — verify your control supply is DC, not AC, because a 230 VAC coil will not pull in on this DC-rated coil.
This variant ships with no MSP auxiliary contact and one normally open contactor auxiliary (1 NO). That is the standard complement for a basic start/stop circuit where the contactor's own NO seals in the coil. If your application requires a second NO for a remote status lamp or a NC for a safety feedback, you will need to add a separate auxiliary contact block that clips onto the S00 contactor side.
