It combines a contactor and a bimetal overload relay in one enclosure, rated for AC-3 motor duty at 0.75 kW at 400 V. The setting range is 1.4 to 2.0 A, with a fixed full-scale value of 2 A. The 0.75 kW AC-3 rating at 400 V tells you this starter is sized for small three-phase induction motors — think fractional-horsepower pumps, fans, or conveyor drives. The 1.4 to 2.0 A setting range matches the full-load current of a 0.75 kW motor at 400 V; you dial the bimetal relay to the motor nameplate FLA. Operating voltage is 400 to 500 V AC, three-phase, covering standard European 400 V and 480 V North American supplies. ## Built-in brake output and bus communication This starter includes a motor brake output rated DC 24 V / 3 A, designed for externally supplied brakes on motors with holding brakes. PROFIBUS DP communication is built in — the starter talks directly to a PLC via the ET 200X backplane, giving you remote start/stop, fault feedback, and current monitoring without hardwiring each motor circuit back to a central cabinet. The enclosure measures 134 mm deep, 140 mm wide, and 270 mm high. It's a standalone block designed for direct mounting on a machine or in a small junction box — not a DIN-rail snap-on unit. Main current connections use tab terminals (fast-on type), which are common for distributed starter blocks in the ET 200X ecosystem. The 9-pole motor feeder and 9-pole power connection are pre-configured for plug-in cabling.","metaTitle":"Siemens 3RK1300-1BS01-0AA1 EM 300 DS direct starter, 1.4-2A,","metaDescription":"Siemens SIRIUS 3RK1300-1BS01-0AA1 electromechanical direct starter, setting range 1.4-2.0A, AC-3 0.75kW/400V, IP65, with brake contact and PROFIBUS DP.
