It integrates motor protection via a bimetal overload relay, PROFIBUS DP communication, and a motor brake output into a single IP65-rated enclosure. Rated for AC-3 duty at 0.12 kW on a 400 V supply, the unit's setting range spans 0.35 to 0.5 A, making it suitable for small reversing motor applications such as conveyor drives or valve actuators in washdown environments. Housed in a 140 x 270 x 134 mm (W x H x D) enclosure rated IP65, this starter mounts directly on machine frames or in field junction boxes — no separate control cabinet required. The IP65 rating means the electronics withstand hose-directed water and dust ingress, so it can sit right on the motor frame in a food or beverage line. Main circuit connections use tab terminals; the unit communicates over PROFIBUS DP and includes a dedicated motor brake output for internally supplied brakes. The 9-pole motor feeder and 9-pole power connection are pre-configured for the ET 200X backplane. ## Electrical ratings and protection The bimetal motor protection covers the 0.35 to 0.5 A range. The operating voltage range is 400 to 500 V DC, and the unit operates in ambient temperatures from 0 to 55 °C. Equipment marking per DIN EN 61346-2 is Q (power switching device). The electromechanical switching contacts are rated for AC-3 motor switching duty at 0.12 kW / 400 V.","metaTitle":"Siemens 3RK1300-0FS01-1AA3 Reversing Starter, 0.35-0.5A, AC-","metaDescription":"Siemens 3RK1300-0FS01-1AA3 EM 300 RS reversing starter, setting range 0.35-0.5A, AC-3 0.12kW at 400V, IP65, PROFIBUS DP, with brake contact.
