Overview
The SIRIUS electronic soft starters are suitable for controlled soft
starting and running down of three-phase asynchronous motors.
Reduction of the starting torque not only protects the motor, but
also increases the availability of the installation.
With just a few actions and accessories, motor feeders can be
fitted with these soft starters for communications capability.
The advantages of a soft starter are:
• Reduction of mechanical loading throughout the drive
• Reduction of the loading on the power supply system

Selection and Ordering data
