Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm to the side, zero forwards or backwards — so the unit fits into a standard 200 mm deep enclosure with no extra stand-off. Sourced through authorized distribution channels; volume pricing and lead time confirmed at RFQ against the BOM quantity. No direct stock-holding claim — each order is quoted individually. The supplied sub-assemblies (contactor 3RT2015-1BB41, circuit-breaker 3RV2011-0FA15, busbar adapter 8US1251-5DS10, link module 3RA1921-1DA00) are individually orderable as spares, but the 3RA2 assembly is the factory-tested combination that guarantees coordination between the overload and short-circuit elements. ## Environmental and compliance range Operating temperature range is -20 to +60 °C; storage -50 to +80 °C; transport -55 to +80 °C — the wider transport window reflects the unit's ability to survive cold-chain logistics without functional damage. Degree of pollution 3 per IEC 60947-1, meaning it tolerates conductive pollution (condensation, occasional light dust) typical of industrial control panels without conformal coating. The auxiliary switch extension option (product extension auxiliary switch = Yes) allows adding a signal contact for PLC feedback or status indication without modifying the main assembly.","metaTitle":"Siemens 3RA2115-0FD15-1BB4 SIRIUS Motor Starter, Size S00","metaDescription":"Siemens 3RA2115-0FD15-1BB4 SIRIUS non-fused motor starter, Size S00, 24 VDC coil, Class 10 thermal overload, 690 V AC-3 max.
