Siemens AG 3VU1300-1MK00 Manual Motor Starter

Siemens 3VU1300-1MK00 is a compact manual motor starter protector that combines motor-start control with thermal overload protection for three-phase motors, designed to be installed in control panels or machine enclosures in demanding industrial environments. The unit includes a built-in auxiliary contact (1NO/1NC) and provides a field-adjustable overload current setting of 4-6 A, enabling precise protection tailored to the protected motor’s starting surge and running current without needing separate devices. As part of Siemens' motor starter protector family, it offers simple, integrated control and signaling for applications where a reliable start sequence and motor protection are critical, reducing wiring complexity and panel footprint. Typical deployments include machine tools, textile machinery, automotive systems, and food processing lines, where operators rely on predictable starting behavior and prompt protection against overloads. The combination of manual actuation with protective circuitry supports straightforward maintenance and diagnostic insight, helping maintain uptime by providing clear electrical separation between start/stop control and motor protection functions.
