SIRIUS direct starter for 60 mm busbar systems
The Siemens 3RA2110-0JD15-1BB4 is a SIRIUS direct-on-line starter in Size S00, designed specifically for snapping onto 60 mm busbar systems — a common panel layout in European-style motor control centres. It ships as a pre-assembled unit containing the 3RT2015-1BB41 contactor, the 3RA1921-1DA00 link module, and the 8US1251-5DS10 busbar adapter, so the BOM line covers the full motor-starting group in one order code.
Mounting and integration — busbar clip, no DIN rail
Mounting position is vertical only; the unit occupies 45 mm width on the busbar, with 155 mm depth and 203 mm height, requiring 50 mm clearance upwards and 20 mm forwards for wiring access. Main circuit connections use screw-type terminals, which means a screwdriver termination — no spring-cage tooling needed, but torque-check each connection per the installation instructions.
Environmental limits and compliance
Rated for operation from -20 to +60 °C with storage and transport tolerance from -50 to +80 °C, covering most indoor panel environments without derating for ambient temperature within that band. RoHS compliance date is 10/01/2009, confirming the starter meets the EU substance restrictions — relevant for OEMs shipping equipment into regulated markets.
