It integrates a motor starter and PROFIBUS DP communication in one IP65-rated package, so it mounts directly on the machine frame or conveyor section — no separate control cabinet needed. Setting range is 0.18 to 0.25 A with a bimetal overload relay, protecting a 0.06 kW motor at 400 V AC-3 duty. The short-circuit breaking capacity is 50 A at 400 V — sufficient for the branch circuit protection when paired with the upstream circuit breaker. ## Fieldbus and connectivity PROFIBUS DP is onboard, so the starter communicates directly with the controller without an extra gateway. Main current connections use tab terminals — quick to land in the field, no screw terminals to torque. The 9-pole motor feeder and 9-pole power connection mate to the ET 200X backplane. IP65 means the housing and the tab terminals are sealed against washdown and dust ingress. This part lives on the machine, not in a panel, so the enclosure rating is what keeps it running in wet or dirty environments.","metaTitle":"Siemens 3RK1300-0CS01-0AA0 EM 300 DS Direct Starter, 0.18-0.","metaDescription":"Siemens 3RK1300-0CS01-0AA0 EM 300 DS direct starter for ET 200X.
