The Siemens 3RA1110-0EA15-1AN6 is a SIRIUS non-fused load feeder configured as a direct starter in size S00. It ships as a pre-assembled combination of a contactor (3RT1015-1AN61), a circuit breaker (3RV1011-0EA10), and a link module (3RA1911-1AA00) — one order code, one assembly, one DIN-rail snap-on mount. The 45 mm wide footprint and 159 mm height fit standard control-panel layouts; the 75 mm depth leaves clearance for wiring ducts or adjacent components.
Motor Protection and Short-Circuit Coordination
Motor protection is handled by a bimetal overload relay built into the feeder, so it tracks thermal load on the motor winding directly. Short-circuit protection uses the supplied circuit breaker rather than fuses — this means the feeder can be reset after a fault without carrying spare fuse links. At 400 V the assembly is rated for 0.09 kW motor output, sized for small pumps, fans, or conveyor drives.
Snap-on mounting to a DIN rail. For airflow and access, plan for 20 mm clearance above, 10 mm in front, 9 mm behind, 20 mm at the side, and 0 mm below.
Main-circuit terminals accept solid or stranded wire from 0.5 to 4 mm², with dual terminals handling 2x 0.75 to 2.5 mm². The control supply runs on 50 to 60 Hz at 200 V (50 Hz) or 200 to 220 V (60 Hz).
