Mounting position is vertical with 20 mm clearance upward and 10 mm downward; zero clearance needed forward or backward, so adjacent components can butt directly against the body. Overall dimensions: 167.2 mm height, 45 mm width, 97.1 mm depth — fits a standard S00 feeder footprint without surprises. ## Motor protection and trip coordination Thermal bimetallic overload release paired with a magnetic short-circuit trip gives two-stage protection: the bimetal tracks motor heating, the magnetic element clears a hard fault instantly. Rated operational voltage up to 690 V AC at AC-3 duty, operating frequency 50/60 Hz — covers most low-voltage motor circuits in European and North American panels. ## Supplied sub-assemblies and wire terminations This direct starter ships with the contactor 3RT2015-1AK61, the link module 3RA1921-1DA00, and the circuit-breaker 3RV2011-0FA15 — three matched components in one order code, no separate sourcing. AWG sizes from 2× 20 to 2× 12, with 2× (18 to 14) for the contactor side. An auxiliary switch expansion slot is built into the product extension, so adding feedback contacts or status signals doesn't require a separate enclosure. ## Environmental and compliance envelope Pollution degree 3 per IEC 60947-1, meaning it tolerates conductive dust and condensation typical in industrial control panels without conformal coating. Rated impulse withstand voltage 6 kV — coordinates with standard surge protection devices at the panel incoming supply.","metaTitle":"Siemens 3RA2115-0FA15-1AK6 SIRIUS Non-Fused Motor Starter","metaDescription":"Siemens SIRIUS 3RA2115-0FA15-1AK6 direct starter, Class 10, 120 W at 400 V, frame size S00.
