SIRIUS S00 direct starter, 5 A AC-3, CLASS 10
The Siemens 3RA2110-1FA15-1BB4 is a SIRIUS direct on-line starter in the Size S00 frame, combining a contactor and overload relay in one unit. The supplied contactor is 3RT2015-1BB41 and the link module is 3RA1921-1DA00 — the whole assembly is pre-coordinated, so you don't need to match components yourself.
Panel fit and clearance dimensions
The starter measures 45 mm wide, 167 mm tall, and 97 mm deep. For ventilation and arc clearance, Siemens specifies 50 mm upwards, 20 mm forwards, 10 mm downwards, and 20 mm at the side — no clearance needed backwards. That 45 mm width is the same as a standard S00 contactor, so it drops into existing panel layouts without re-spacing.
