It integrates a bimetal motor protection relay with an adjustable setting range of 1.4...2.0 A, and delivers 0.75 kW at 400 V under AC-3 duty, making it suitable for switching three-phase induction motor loads in a compact, IP65-rated enclosure. The PROFIBUS DP interface enables direct communication with a PLC over the fieldbus, eliminating separate I/O wiring for start/stop and feedback signals. The setting range of 1.4...2.0 A determines the motor full-load current the bimetal relay protects. For a 0.75 kW motor at 400 V, the full-load current typically falls near 1.9 A; the 2.0 A top of the range gives a small margin above the motor nameplate, which is standard practice to avoid nuisance tripping on inrush. AC-3 rated at 0.75 kW at 400 V confirms this starter is intended for starting squirrel-cage motors under normal starting conditions — not for frequent reversing or plugging. The operating voltage range is 400...500 V, covering standard 400 V three-phase networks across Europe and many 480 V installations. The maximum short-circuit breaking capacity (Icu) at 400 V is 50 A. In a panel with a 50 A or larger feeder, this starter provides full selectivity for motor branch circuits. Dimensions of 134 mm depth, 140 mm width, and 270 mm height mean it occupies a standard footprint within the ET 200X module row. The 9-pole motor feeder and 9-pole power connection are tab terminals for fast wiring. The design includes a bus communication function via PROFIBUS DP, so the starter is addressed and parameterized through the fieldbus network. No AS-Interface — the communication is strictly PROFIBUS. There is no motor brake output, so if the application requires a holding brake, an external brake contactor must be added. Because this is an active, current-production item, sourcing is straightforward through the usual Siemens industrial automation channel.","metaTitle":"Siemens 3RK1300-1BS01-0AA0 EM 300 DS direct starter, 1.4-2.0","metaDescription":"Siemens 3RK1300-1BS01-0AA0 EM 300 DS electromechanical direct starter for ET 200X.
