Rated operational power at 400 V is 60 W, at 500 V also 60 W, and at 690 V it reaches 90 W — these are the motor power limits the starter can switch and protect under those line voltages. Snap-mounts onto 35 mm DIN rail or can be screw-mounted using an additional push-in lug — the same unit serves both new builds and retrofit panels. Mounting position is vertical only; the unit is 45 mm wide, 97.1 mm deep, and 167.2 mm high, with 20 mm clearance required above and 10 mm below for ventilation and wiring. Degree of pollution 3 means it is rated for industrial environments with conductive dust or occasional condensation — no additional conformal coating needed for typical panel conditions. The supplied contactor (3RT2015-1BB41) and circuit breaker (3RV2011-0BA15) are standard SIRIUS components, so replacement parts and spares are widely stocked in the supply base.","metaTitle":"Siemens 3RA2115-0BA15-1BB4 SIRIUS Motor Starter, Size S00","metaDescription":"Siemens 3RA2115-0BA15-1BB4 SIRIUS non-fused motor starter, Size S00, Class 10, 24 V DC coil, 3-pole, 45 mm wide.
