What this SIRIUS direct starter delivers
The 3RA2115-1EE15-1FB4 is a Siemens SIRIUS direct-on-line starter in size S00, combining a 3RT2015-2FB41 contactor with a 3RV2011-1EA25 circuit-breaker and a thermal bimetallic overload relay in a single assembly.
Mounting and panel fit
The supplied link module 3RA2911-2AA00 pre-wires the contactor to the circuit-breaker, so the assembly arrives as a single unit ready for rail mounting and power connection.
Protection design and operating limits
The overload release is thermal bimetallic (ambient-compensated -20 to +60 °C), while the short-circuit trip is magnetic — together they provide motor overload and short-circuit protection in one footprint. Rated surge voltage resistance 6 kV, operating humidity 10 to 95 %, and storage/transport temperature range -50 to +80 °C — the starter handles typical industrial panel environments without derating.
