It is an electromechanical direct starter with a bimetal motor protection element, setting range 0.45...0.63 A, rated for AC-3 duty at 0.18 kW at 400 V (operating voltage 400...500 V). The IP65 enclosure means it withstands washdown and dusty environments — suitable for standalone mounting on machine frames or in wet-area panels without an additional enclosure. ## PROFIBUS DP and brake integration This starter includes bus communication via PROFIBUS DP, so it connects directly to the ET 200X backplane and participates in cyclic I/O data exchange without a separate gateway. The integrated motor brake output (product component motor brake output) supplies an internally fed brake through the 9-pole motor feeder and 9-pole power connection — a single cable run from the starter to the motor handles both power and brake control, saving a separate brake rectifier and reducing wiring in the field. ## Short-circuit protection and breaking capacity The short-circuit protection design uses circuit-breakers (not fuses), and the maximum short-circuit breaking capacity (Icu) at 400 V is rated at 50 A. That figure governs the upstream protective device selection — the starter itself can interrupt a fault up to 50 A at 400 V, so the branch circuit must be coordinated to keep let-through energy within that limit. Operating temperature range is 0...55 °C; above that, derate the thermal setting.","metaTitle":"Siemens 3RK1300-0GS01-0AA3 EM 300 DS Direct Starter, 0.45-0.","metaDescription":"Siemens SIRIUS EM 300 DS direct starter, setting range 0.45-0.63A, AC-3 0.18kW/400V, IP65, PROFIBUS DP, integrated brake output.
