Siemens develops quality, innovative products that monitor, control, and protect motors for any environment. We implement smart technology to boost their performance and make motors dependable without failure. This helps create an energy-efficient environment for you and for the world. Since motors play a critical role in your processes, their performance must be both optimal and dependable without failure. Siemens 3RE47 enclosed soft starters ensure that! They help limit the starting current and torque to best fit your application.

The motor is adjusted to the load of the driven machine by means of stepless control of the voltage supply. Mechanical equipment is accelerated softly which improves process performance, reduces wear and tear, and extends life of equipment. Furthermore, brownouts, current spikes, and other disturbances to the electrical grid are minimized.
