It is rated 550 W at 400 V (50/60 Hz) with a Class 10 trip curve, meaning it protects standard induction motors against overload while allowing them to start loads with moderate inertia. The unit ships with the 3RT2015-1AK61 contactor and the 3RA1921-1DA00 link module pre-assembled — a matched pair that avoids coordination guesswork at the panel build stage. ## Mounting and panel fit Mounting position is vertical only; the unit requires 20 mm clearance above and 10 mm below for airflow and wiring access, with zero clearance needed at the sides or front/back. Operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C — suitable for unheated enclosures in temperate climates as long as condensation is managed. ## Rated power and current across voltages At 400 V AC-3 duty the starter delivers 550 W; at 480 V the rated current is 1.6 A, at 600 V it drops to 1.3 A — the thermal overload element is calibrated for the motor FLA at the applied line voltage. Horsepower ratings are 0.1 hp at 230 V and 0.75 hp at both 460/480 V and 575/600 V — the starter matches NEMA motor frames up to that output.","metaTitle":"Siemens 3RA2115-1AA15-1AK6 SIRIUS Motor Starter","metaDescription":"Siemens 3RA2115-1AA15-1AK6 SIRIUS non-fused motor starter, 550 W at 400 V, Class 10 thermal overload, size S00.
