Rated at 0.75 kW in AC-3 duty at 400 V, it switches standard three-phase squirrel-cage motors up to that power. The bimetal overload sets between 1.4 A and 2.0 A full-scale, matching the motor full-load current for that power class. The operating voltage range is 400...500 V AC. Built-in PROFIBUS DP communication lets the starter exchange status and control signals directly with a PLC over the fieldbus, eliminating separate I/O wiring for each motor branch. The main circuit connects via tab terminals, which is the standard faston-style interface for the ET 200X power bus. Dimensions are 140 mm wide, 270 mm high, 134 mm deep. The IP65 enclosure is self-contained — no DIN-rail mounting required; it bolts directly to a machine frame or mounting plate. The 134 mm depth is the critical dimension for shallow enclosures or tight spaces between machine guards. Tab terminals for the main circuit match the standard ET 200X power tap-off system, so panel builders can plug it into the pre-wired power bus without cutting and crimping individual wires. ## Short-circuit coordination The maximum short-circuit breaking capacity (Icu) at 400 V is 50 A. The short-circuit protection design uses circuit-breakers, not fuses, so the coordination is with a molded-case or miniature circuit breaker upstream. Ambient operating range is 0...55 °C.","metaTitle":"Siemens 3RK1300-1BS01-1AA0 reversing starter, 0.75 kW, IP65","metaDescription":"Siemens SIRIUS 3RK1300-1BS01-1AA0 electromechanical reversing starter, 0.75 kW at AC-3 400 V, setting range 1.4...2.0 A, IP65, PROFIBUS DP.
