The Siemens 3RA1210-0FA15-0AF0 is a SIRIUS non-fused load feeder configured as a reversing starter, size S00, designed to control the forward and reverse direction of a three-phase motor from a single assembly. Rated at 0.12 kW at 400 V, it uses a bimetal overload relay for motor protection and integrates a supplied circuit breaker (3RV10 11-0FA10) for short-circuit protection, a contactor (3RT10 15-1AF02), and a link module (3RA19 11-1AA00) into one package.
Snap-on fastening onto a 35 mm standard DIN rail is the mounting method, with a horizontal mounting position specified. Dimensions are 90 mm wide, 159 mm high, and 75 mm deep, with clearance requirements of 20 mm upward, 10 mm forward, 9 mm backward, 20 mm at the side, and 0 mm downward for ventilation and wiring access. Terminal capacity accepts solid or stranded conductors from 0.5 to 4 mm², with dual-wire capability for 2x (0.75 to 2.5 mm²) on the main contacts, and AWG equivalents of 2x (18 to 14).
The reversing starter is supplied as a complete assembly including the contactor, circuit breaker, link module, and RH assembly kit (3RA19 13-2A), which simplifies BOM management and panel wiring.
