The SIEMENS 3RK4* SIRIUS Motor Starter MCU product line features motor starters with enclosures rated IP54 or IP55, constructed from plastic or metal. These starters incorporate short-circuit protection with a circuit breaker, often utilizing a bimetal or bimetal-thermal mechanism. Communication is typically facilitated through AS-Interface, and switching is often electromechanical, although electronic switching is also available. They offer both direct-on-line and reversing starter configurations, and may include a brake function.
