The setting range covers 3.5 to 5.0 A, with bimetal overload protection built in. It includes an integrated brake output rated DC 24 V / 3 A for externally supplied brakes, and communicates via PROFIBUS DP. The IP65 enclosure means the unit is suited for washdown or dusty environments — no separate cabinet needed if the area is rated for it. ## Integration Notes The main current circuit connects via tab terminals; the 9-pole motor feeder and power connection are pre-wired for a standard reversing scheme. The PROFIBUS DP interface allows direct connection to a PLC without a separate gateway, reducing cabinet wiring. The maximum short-circuit breaking capacity at 400 V is 50 A — coordinate upstream protection accordingly.","metaTitle":"Siemens 3RK1300-1FS01-1AA1 Reversing Starter, 3.5-5A, 1.9kW,","metaDescription":"Siemens SIRIUS 3RK1300-1FS01-1AA1 electromechanical reversing starter, 3.5-5A, 1.9kW at AC-3 400V, IP65, PROFIBUS DP, integrated brake output.
