Reversing starter, size S00 — what it integrates
The Siemens 3RA2210-0FA15-2BB4 is a SIRIUS reversing starter in size S00, combining a contactor, thermal overload relay, and mechanical interlock in one assembly for forward/reverse motor control. It ships with the supplied contactor 3RT2015-1BB42 and link module 3RA1921-1DA00, so the reversing pair is pre-assembled and tested — no separate interlock wiring needed.
Thermal overload and trip coordination
The short-circuit trip is magnetic, providing instantaneous protection against high fault currents; the combination covers both overload and short-circuit in a single device. Operating temperature range is -20 to +60 °C, with storage and transport limits from -50 to +80 °C — suitable for unheated warehouses and container shipments.
Mounting and panel fit
Depth is 97 mm; clearance requirements are 50 mm upwards, 32 mm forwards, 10 mm downwards, and 10 mm at the side — plan the enclosure depth and cable duct placement accordingly. Main circuit connections use screw-type terminals, rated for 50/60 Hz operation — standard for panel wiring with ring or fork lugs.
