It ships as a pre-assembled unit containing a 3RT10 15-1AF02 contactor, a 3RV10 11-1HA10 circuit breaker for short-circuit and overload protection, a 3RA19 11-1AA00 link module, and a 3RA19 13-2A RH assembly kit — essentially a complete reversing motor start and protection package in one footprint. Motor protection is handled by a bimetal overload relay integrated into the circuit breaker, so no separate overload is needed. The enclosure measures 90 mm wide by 159 mm high by 75 mm deep, with IP20 finger-safe protection on the front — suitable for enclosed control panels where the front face is the only accessible surface. Clearance requirements around the unit: 20 mm upward, 10 mm forward, 9 mm backward, 0 mm downward, and 20 mm at the sides — tight enough for dense panel layouts but the 20 mm side gap needs to be maintained for cooling and arc flash containment. Wire termination accepts solid or stranded conductors from 0.5 to 4 mm² (single) or 2x 0.75 to 2.5 mm² (two conductors per clamp), with AWG equivalent of 2x 18 to 14 for the main contacts. ## Electrical ratings and environment The control coil is rated for 110 V at 50 Hz; no PROFINET or PROFIBUS DP protocol support is built in — this is a conventional electromechanical reversing starter, not a fieldbus-controlled soft starter. Operating temperature range is -20 to +70 °C, storage from -55 to +80 °C, and it withstands shock up to 9.8g — robust enough for most industrial cabinet environments but not rated for direct machine-mount vibration without additional damping. No-load mechanical switching frequency is rated at 15 operations per second — a figure that applies to the contactor mechanism unloaded, not to motor starting duty where the thermal limits of the bimetal relay govern.","metaTitle":"Siemens 3RA1210-1HA15-0AF0 SIRIUS Reversing Starter","metaDescription":"Siemens SIRIUS 3RA1210-1HA15-0AF0 non-fused reversing starter, size S00.
