The Siemens SIRIUS 3RA1210-0JC15-0AF0 is a non-fused load feeder configured as a reversing starter, size S00. It integrates a contactor, a bimetal motor-protection relay, and a reversing link module into one package — so one order code covers the reversing pair, the overload, and the mechanical interlock. Rated 0.25 kW at 400 V, it handles small reversing motor loads like conveyors, gate drives, or pump direction changes.
Mounts by snapping onto 40 mm center-to-center busbar systems — the standard SIRIUS S00 footprint. Dimensions are 90 mm wide, 203 mm high, 128 mm deep. Clearance requirements: 20 mm above, 10 mm in front, 9 mm behind, 0 mm below, 20 mm at the sides. Mounting position is horizontal only.
Main circuit terminals accept solid or stranded wire 0.5 to 4 mm², or 2x 0.75 to 2.5 mm². AWG equivalents: 2x 18 to 14 AWG for the main contacts. The spring-cage or screw terminals (depending on the supplied contactor variant) are sized for the S00 frame.
