Clearance requirements: 50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side — plan these gaps in the enclosure to maintain airflow and wiring access. Mounting position is vertical only; the supplied link module 3RA1921-1DA00 connects the contactor and circuit-breaker mechanically and electrically. ## Protection and trip coordination The short-circuit trip is magnetic (instantaneous), the overload release is thermal (bimetallic) — together they provide Type 2 coordination per IEC 60947-4-1, meaning the starter survives a short-circuit without damage to the contactor. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C — the starter can sit in an unheated warehouse or be shipped in winter without issue. The contactor and circuit-breaker are supplied as part of the assembly — no separate ordering of those components is needed for a drop-in replacement.","metaTitle":"Siemens 3RA2115-0EA16-2BB4 SIRIUS Motor Starter","metaDescription":"Siemens 3RA2115-0EA16-2BB4 SIRIUS direct-on-line motor starter, 90 kW at 400 V AC-3, Class 10, size S00.
