Panel integration — S00 busbar feeder
The 3RA1110-0HC15-1AF0: This is a fully assembled non-fused load feeder (direct starter) from the SIRIUS S00 family, combining a contactor, a bimetal overload relay, and a circuit-breaker short-circuit protection element in one package. It snaps directly onto a 40 mm busbar system via the supplied busbar adapter (8US1051-5DM07), saving DIN-rail space and reducing wiring. The IP20 front protection is standard for enclosed panel mounting.
Rated for the motor branch
Rated at 0.18 kW at 400 V (50 Hz), this feeder is sized for small three-phase induction motors — think conveyor drives, small pumps, or fan starters. The 110 V 50 Hz coil voltage is common in North American control circuits stepped down from a 480 V line; verify your control transformer taps. The supplied contactor is a 3RT1015-1AF01 and the supplied circuit-breaker is a 3RV1011-0HA10, both S00 frame, so the coordination between overload and short-circuit protection is pre-validated by Siemens.
