It integrates a contactor, bimetal motor protection, and short-circuit protection into a single IP65-rated enclosure, so it mounts directly on the machine or in the field — no separate control cabinet needed for this motor branch. The setting range of 0.55...0.8A and AC-3 rating of 0.21 kW at 400 V mean it is sized for small three-phase induction motors — pumps, fans, conveyors — where the full-load current falls within that window. The bimetal overload relay provides thermal memory for starting under load; the integrated circuit-breaker-style short-circuit protection clears faults up to 50 A at 400 V (Icu). This unit includes a motor brake output, so it can control an internally supplied DC brake on the motor — common for holding loads on vertical axes or conveyors. The main current circuit connects via tab terminals; the 9-pole motor feeder and 9-pole power connection are part of the ET 200X plug-in architecture. PROFIBUS DP is onboard for communication back to the PLC, eliminating a separate fieldbus coupler for this motor starter. ## IP65 and field-mount deployment The 270 mm height, 140 mm width, and 134 mm depth fit the ET 200X form factor; it bolts to a mounting plate or machine frame, not a DIN rail. Ambient operating temperature range is 0 to 55 °C. ## SCCR and coordination note The maximum short-circuit breaking capacity (Icu) at 400 V is 50 A. This is the fault current the integrated short-circuit protection can interrupt without external fusing. The short-circuit protection design uses circuit-breakers (integrated), not separate fuses.","metaTitle":"Siemens 3RK1300-0HS01-0AA3 EM 300 DS Direct Starter, 0.55-0.","metaDescription":"Siemens 3RK1300-0HS01-0AA3 EM 300 DS direct starter, setting range 0.55-0.8A, 0.21kW at AC-3/400V, IP65, PROFIBUS DP, with brake contact.
