The Siemens 3RA8411-1KE10 is a SIRIUS 3RA8 intelligent load feeder configured as a direct starter with high feature functionality. It ships as a pre-assembled kit consisting of three components: a 3RC7140-1KE10 communication module, a 3RV2311-1KC20 circuit breaker, and a 3RT2017-2BB42 contactor. The assembly is rated for motor currents from 1.2 A up to 12 A at voltages up to 690 V AC, with type of coordination 1. It mounts on the ET 200SP distributed I/O system backplane, making it a drop-in motor starter for Siemens PROFINET or PROFIBUS remote racks.
The 1.2-12 A current range covers standard small induction motors up to about 5.5 kW at 400 V — think pumps, fans, and small conveyors. The 690 V AC rating means it handles 480 V or 575 V line supplies common in North American and Canadian panels without derating. The ET 200SP compatibility is the key integration constraint: this load feeder is not a standalone DIN-rail device. It slots directly onto the ET 200SP backplane bus, sharing power and PROFINET communication with the I/O modules in the same rack. If your panel uses ET 200SP distributed I/O, this saves wiring and cabinet space versus a separate contactor + overload + motor starter combination.
