Siemens 3RK1300-0HS01-0AA0 Soft Starter Module

Siemens 3RK1300-0HS01-0AA0 EM 300 DS Direct Starter is an electromechanical motor starter for direct-on-line starting of small 3‑phase motors. The 3RK1300-0HS01-0AA0 designation identifies an EM 300 DS direct starter configured for AC‑3 duty with a setting range of 0.55 to 0.8 A and a rated power of 0.21 kW at 400 V, and it is supplied without a brake contact. This version is used in ET 200X installations as a Direct Starter module within Siemens’ SIMATIC ecosystem, providing a compact solution for basic motor control tasks in control panels or distributed I/O configurations. It supports line switching for loads in the 400 V AC range within the 0.55–0.8 A window, enabling straightforward, reliable starting and stopping without brake circuitry; the lack of a brake contact makes it a simpler, lower-cost option in the EM 300 DS family. The 0HS01‑0AA0 variant is the configuration that excludes braking functionality, aligning with applications that require direct switching only and no brake release control.
