It integrates a motor starter, bimetal overload protection, and a brake output into a single IP65-rated enclosure, making it suitable for direct-on-line starting of motors up to 5.5 kW at 400 V AC-3 duty. The setting range of 9...12 A defines the full-load current window for the bimetal overload relay — set it to the motor nameplate FLA. The AC-3 rating of 5.5 kW at 400 V covers standard 4-pole induction motors in that power class; the operating voltage range of 400...500 V means it works on 400 V and 480 V networks without a tap change. The 9-pole motor feeder and 9-pole power connection handle the motor leads plus brake wiring in one plug. The integrated brake contact is rated for DC 500 V / 1 A, sized for internally supplied DC brakes common on small servo and asynchronous motors. The PROFIBUS DP interface lets the starter communicate directly with a PLC over the fieldbus, eliminating point-to-point control wiring.","metaTitle":"Siemens 3RK1300-1KS01-0AA4 EM 300 DS Direct Starter, 9-12A,","metaDescription":"Siemens 3RK1300-1KS01-0AA4 EM 300 DS electromechanical direct starter, setting range 9-12A, AC-3 5.5kW/400V, IP65, with brake contact and PROFIBUS DP.
