It combines motor starting, bimetal overload protection, and PROFIBUS DP communication in a single IP65-rated enclosure, so it can be mounted directly on the machine frame rather than in a central cabinet. Rated for AC-3 duty at 400 V, it switches a 0.55 kW motor load and has an adjustable full-scale current range of 1.1 to 1.6 A. ## Fieldbus and brake integration The starter includes a built-in PROFIBUS DP interface for direct connection to the control network, eliminating the need for a separate gateway module. It also has a motor brake output for internally supplied brakes — a common requirement on vertical-axis or high-inertia conveyor drives where the load must hold position when power is removed. Physical footprint is 140 mm wide, 270 mm high, and 134 mm deep — sized to fit the ET 200X mounting rail. The equipment marking per DIN EN 61346-2 (Q) identifies it as a motor starter in the schematic.","metaTitle":"Siemens 3RK1300-1AS01-0AA3 EM 300 DS direct starter, 1.1-1.6","metaDescription":"Siemens 3RK1300-1AS01-0AA3 EM 300 DS electromechanical direct starter for ET 200X.
