It combines a motor starter, overload protection via bimetal, and a brake output in one IP65-rated enclosure, so it mounts directly on the machine frame or conveyor section — no separate control cabinet needed for the motor branch. The setting range covers 0.14 to 0.2 A (full-scale 0.2 A), which in AC-3 duty at 400 V translates to a motor rating of 0.06 kW. That is a small fractional-horsepower motor — think a compact conveyor drive, a small agitator, or a valve actuator on a food-and-beverage line where the IP65 washdown rating matters. It communicates over PROFIBUS DP, so it integrates into a Siemens S7-300/400 or ET 200X remote rack as a smart motor starter with diagnostics. The operating voltage range is 400 to 500 V AC, and the short-circuit breaking capacity at 400 V is 50 A — enough to clear a fault on the branch without taking out the upstream feeder. ## Motor brake output and wiring This variant includes a motor brake output (product component Motor brake output = Yes), meaning it can directly control a DC-injected brake on the motor — common for holding loads on inclined conveyors or vertical axes. The main current circuit connects via tab terminals, and the 9-pole motor feeder and 9-pole power connection are pre-configured for the ET 200X backplane. The enclosure measures 134 mm deep by 140 mm wide by 270 mm high — a compact footprint that fits a standard machine-mount junction box or a small IP65 sub-panel. If you need a drop-in for an existing ET 200X node, this is the exact order code; there is no direct second-source that matches the form factor and communication profile.","metaTitle":"Siemens 3RK1300-0BS01-0AA3 EM 300 DS Direct Starter, 0.14-0.","metaDescription":"Siemens 3RK1300-0BS01-0AA3 EM 300 DS electromechanical direct starter for ET 200X.
