It combines a solid-state overload relay, a motor starter protector, and two contactors into one unit that mounts directly on the ET 200SP distributed I/O system. The current range spans 1.2 A to 12 A, and it's rated for voltages up to 690 V AC with type of coordination 1 — meaning it clears a short-circuit fault without damage to the starter, though the contactor may need replacement after a major fault. Frame size S00 keeps the footprint compact for high-density panels. The assembly includes four components: the 3RC7141-1KE00 intelligent overload relay with IO-Link communication, the 3RV2311-1KC20 motor starter protector for short-circuit and overload protection, and two 3RT2017-2BB42 contactors for forward and reverse direction switching. Everything arrives pre-wired and tested, so it's a single order code for the BOM rather than sourcing four separate parts. ## Deployment context This reversing starter is designed to plug directly into the ET 200SP backplane bus, which means it communicates over PROFINET or PROFIBUS via the head module. The S00 frame size matches the standard ET 200SP width, so it fits in the same DIN-rail layout as digital I/O modules. For a panel builder, this saves the wiring time of a traditional reversing contactor setup — the power and control connections route through the backplane, and the motor cables terminate at the top of the unit.","metaTitle":"Siemens 3RA8511-1KE00 SIRIUS intelligent load feeder","metaDescription":"Siemens 3RA8511-1KE00 SIRIUS intelligent load feeder reversing starter.
