It combines a contactor, bimetal motor protection, and a motor brake output in one IP65-rated enclosure — a self-contained motor start/stop and protection unit for a single motor load. The setting range is 0.35 to 0.5 A, and at AC-3 duty (squirrel-cage motor starting) on a 400 V supply it is rated for 0.12 kW. That 0.12 kW figure is the motor power it can switch under the standard AC-3 utilization category — the rating that governs real motor starting, not a resistive load. It communicates over PROFIBUS DP, so it integrates directly into a PROFIBUS network without a separate gateway. The main current circuit connects via tab terminals — quick-connect blades, not screw clamps — which is typical for the ET 200X form factor. This direct starter is built for the ET 200X distributed I/O system — it mounts onto the ET 200X backplane or motor feeder module, not on a DIN rail. Dimensions are 134 mm deep, 140 mm wide, and 270 mm high. The 9-pole motor feeder and 9-pole power connection are part of the ET 200X interface — the starter plugs into the system bus and power rail. ## Protection and breaking capacity Motor protection is via a bimetal overload relay integrated into the starter — it tracks motor current and trips on sustained overload. Short-circuit protection is designed for circuit-breakers upstream, and the maximum short-circuit breaking capacity (Icu) at 400 V is 50 A. The integrated motor brake output (product component Motor brake output = Yes) means this starter can control an externally supplied brake — typically a DC brake coil on a motor — without a separate brake contactor. The brake contact is rated for the same 400-500 V supply as the main circuit.","metaTitle":"Siemens 3RK1300-0FS01-0AA3 EM 300 DS Direct Starter, 0.35-0.","metaDescription":"Siemens SIRIUS 3RK1300-0FS01-0AA3 EM 300 DS direct starter, setting range 0.35-0.5A, AC-3 0.12kW/400V, IP65, PROFIBUS DP, with brake contact.
