It ships as a pre-assembled unit containing the 3RT2015-1AK61 contactor, the 3RA1921-1DA00 link module, and the 8US1251-5DS10 busbar adapter — ready to snap onto a 60 mm busbar system. Rated for motor loads up to 750 W at 400 V (AC-3), with a maximum operational voltage of 690 V. The Class 10 trip characteristic means it will disconnect before the motor windings overheat during a locked-rotor start — a standard spec for general-purpose conveyor and pump drives. ## Motor ratings across common supply voltages At 400 V, the starter handles 750 W; at 500 V, it handles 1 100 W. Horsepower ratings are given for 200/208 V (0.5 hp), 220/230 V (0.5 hp), 460/480 V (1 hp), and 575/600 V (1.5 hp). Current ratings at 480 V and 600 V are 2.15 A and 2.24 A respectively — these are the AC-3 values that govern the contactor's switching life under motor load. The coil operates on 93.5–121 V at 50 Hz and 96–132 V at 60 Hz — a wide enough band to handle nominal 110 V control circuits with tolerance. ## Panel fit and mounting constraints Width is 45 mm, depth 155.1 mm, height 200 mm. The unit snaps onto a 60 mm busbar system and mounts vertically — no adapter plate needed for standard DIN-rail panels. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm to the side. Zero clearance forwards and backwards — the housing is flush-mount rated. Operating temperature range is -20 to +60 °C; storage range is -50 to +80 °C. Pollution degree 3 means it's rated for industrial environments with conductive dust or moisture. The pre-assembled configuration (contactor + link module + busbar adapter) reduces procurement line items and panel wiring labor.","metaTitle":"Siemens 3RA2115-1CD15-1AK6 SIRIUS Motor Starter","metaDescription":"Siemens 3RA2115-1CD15-1AK6 SIRIUS non-fused motor starter, 750 W at 400 V, Class 10, 45 mm wide.
