SIRIUS reversing starter for 60 mm busbar systems
The Siemens 3RA2210-1CH15-2AP0 is a SIRIUS reversing starter in Size S00, designed to snap directly onto 60 mm busbar systems — no DIN rail adapter needed. It ships as a pre-assembled unit with the 3RT2015-2AP02 contactor and 3RA2911-2AA00 link module, so the reversing interlock and mechanical linkage are already in place. The main circuit uses spring-loaded terminals, which cuts wiring time compared to screw-clamp versions — no torque driver needed on the line and load connections.
Class 10 thermal protection and motor ratings
Rated at 0.25 hp at 230 V and 0.75 hp at 400 V, this starter covers fractional-horsepower reversing applications like small conveyors, valve actuators, and hoist drives.
Panel fit and mounting clearances
Dimensions are 155 mm deep, 90 mm wide, 260 mm tall — the width is tight enough to fit multiple units side-by-side on a standard 60 mm busbar run. Required clearances for heat dissipation: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, and 0 mm backwards (the back sits flush against the busbar). Mounting position is vertical only — horizontal installation changes the thermal profile of the overload relay and is not supported.
Operating temperature range is -20 to +60 °C, with storage and transport limits from -50 to +80 °C — standard for panel-mounted industrial gear in non-conditioned spaces.
