AS-Interface Slaves

AS-Interface motor starters and IP20 load feeders

SIRIUS soft starters

■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
