Energy-efficient motor starters and soft starters

Avoid current peaks

We can offer you energy-efficient motor starters and soft starters for all applications. Our communication-capable SIRIUS motor starters and soft starters are the optimal choice for switching, protecting, and monitoring motors. Direct and reversing starters as well as soft starters handle the entire range, from a high number of switching operations to soft starting and soft stopping without mechanical and electrical peaks.

SIRIUS soft starters

Thanks to their measuring functions and communication capability, 3RW44 soft starters and High Feature motor starters can supply measured energy data to higher-level energy management systems. They also can slash mechanical and electrical peak loads by up to 60 percent, and have an extremely low intrinsic power loss. With our soft starter, intelligent, integrated bypass functions can reduce the intrinsic power loss by up to 92 percent. This means that for continuous operation and at a fixed speed, this starter represents a simple and practical solution that plays a decisive role in reducing power costs.

From the basic SIRIUS contactor combinations to pre-wired, fuseless load feeders and soft starters to motor starters for the distributed SIMATIC ET 200S and ET 200pro I/O: without exception, our energy-efficient motor starters and soft starters are remarkably space-saving and can be quickly installed and simply connected to the automation system via AS-Interface, PROFIBUS, or PROFINET. High Feature motor starters can supply measured energy data to higher-level energy management systems. As a result, they provide a simple and practical solution for continuous-operation and fixed-speed equipment, and play a significant role in reducing energy costs.
