It integrates a contactor, bimetal overload relay, and PROFIBUS DP communication in a single IP65-rated enclosure — meaning it can be mounted directly on the machine or conveyor section, not just inside a central panel. The setting range of 2.8...4.0 A covers small motors up to 1.5 kW at 400 V in AC-3 duty (squirrel-cage induction motors), and the integrated motor brake output (DC 500 V/1 A) handles internally supplied brakes without an external relay. The short-circuit breaking capacity (Icu) is 50 A at 400 V, so it coordinates with a 50 A upstream circuit breaker; if your fault current exceeds that, you need a current-limiting device upstream. ## Deployment context The 9-pole motor feeder and 9-pole power connection (tab terminals) are pre-wired for quick connectorization. The PROFIBUS DP interface allows the starter to be controlled and monitored from the PLC without separate control wiring. Ambient temperature range is 0...55 °C during operation, so it can live in a non-conditioned production area.","metaTitle":"Siemens 3RK1300-1ES01-0AA4 EM 300 DS direct starter, 2.8-4 A","metaDescription":"Siemens 3RK1300-1ES01-0AA4 EM 300 DS electromechanical direct starter, setting range 2.8-4.0 A, AC-3 1.5 kW at 400 V, with brake contact, PROFIBUS DP, IP65.
