It integrates motor starting, bimetal overload protection, and PROFIBUS DP communication into a single IP65-rated enclosure for remote or decentralized panel mounting. The setting range covers 1.8 to 2.5 A, with an AC-3 motor rating of 0.9 kW at 400 V — meaning it directly switches and protects a motor load up to that current in a standard three-phase induction motor application. Operating voltage is rated 400 to 500 V DC for the control circuit, and the unit includes a motor brake output rated DC 500 V / 1 A for internally supplied brakes, connected via a 9-pole motor feeder and 9-pole power connection using tab terminals. At 140 mm wide, 270 mm high, and 134 mm deep, this starter occupies a defined footprint within the ET 200X system. The IP65 rating means the enclosure and all connections withstand washdown environments — suitable for food-and-bev, material handling, or any line where hose-down cleaning is routine. Ambient temperature range of 0 to 55 °C covers most unconditioned cabinet environments.","metaTitle":"Siemens 3RK1300-1CS01-0AA4 EM 300 DS Direct Starter, 1.8-2.5","metaDescription":"Siemens 3RK1300-1CS01-0AA4 EM 300 DS direct starter for ET 200X.
