It integrates motor starting, bimetal overload protection, and short-circuit protection via circuit-breakers into a single IP65-rated enclosure, making it suited for on-machine mounting in washdown environments. The setting range covers 0.18 A initial to 0.25 A full-scale, corresponding to a motor rating of 0.06 kW at 400 V AC-3 duty. That AC-3 rating means it's sized for starting squirrel-cage induction motors under load — the typical case for conveyors, pumps, and small fans on a distributed line. Operating voltage is 400–500 V, and the maximum short-circuit current breaking capacity (Icu) at 400 V is 50 A, which governs the upstream protection coordination. The unit includes a motor brake output rated DC 24 V/3 A for externally supplied brakes, and communicates via PROFIBUS DP. ## Deployment context The dimensions (134 mm deep, 140 mm wide, 270 mm high) and tab-terminal main circuit connections are designed for the ET 200X mounting rail system, not a standard DIN rail. Ambient operating temperature is 0 to 55 °C, which covers most conditioned and unconditioned plant-floor environments but not freezer or outdoor desert applications without derating. The equipment marking per DIN EN 61346-2 is Q, identifying it as a switching device in the schematic.","metaTitle":"Siemens 3RK1300-0CS01-0AA1 Direct Starter, 0.18–0.25 A, IP65","metaDescription":"Siemens 3RK1300-0CS01-0AA1 EM 300 DS direct starter, setting range 0.18–0.25 A, 0.06 kW at 400 V AC-3, IP65, with PROFIBUS DP and brake output.
