SIRIUS reversing starter — Size S00, CLASS 10, spring-loaded terminals
The 3RA2210-1GE15-2AP0 is a Siemens SIRIUS reversing starter in Size S00, combining a contactor pair and overload relay in one assembly for forward/reverse motor control. It ships with the 3RT2015-2AP02 contactor and 3RA2911-2AA00 link module pre-integrated. The main current circuit uses spring-loaded terminals (cage-clamp style), which eliminates screw-torque verification during panel build and resists loosening under thermal cycling.
Mounting and panel fit — DIN rail and screw options
The envelope is 97 mm deep, 90 mm wide, and 204 mm tall — the width is the critical dimension when laying out multiple starters side-by-side on the rail. Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, and 10 mm at the side. Backwards clearance is 0 mm — the unit can sit flush against the back panel. These are the minimum air gaps for arc flash containment and thermal dissipation; a panel layout that violates them invalidates the UL/IEC coordination.
Motor horsepower coverage across common voltages
At 230 V rated value the starter covers 0.75 hp, at 200/208 V it covers 1.5 hp, at 220/230 V it covers 2 hp, at 460/480 V it covers 3 hp, and at 575/600 V it covers 5 hp. The 400 V rated value is listed as 2 200 kW — this appears to be a data anomaly; the 480 V figure of 4.8 A and the 600 V figure of 6.1 A are the load-current limits to size against. This is a single-voltage coil — no tap-changing for 240 V or 208 V grids.
Environmental limits and storage
Operating temperature range is -20 to +60 °C, with temperature compensation active across the same band. Storage and transport limits extend from -50 to +80 °C — the wider storage envelope allows the starter to sit in an unheated warehouse or truck without damage.
