■ Overview
The solid-state SIRIUS soft starters are suitable for controlled
soft starting and ramp-down of three-phase asynchronous mo-
tors. The reduction of the starting torque not only protects the
motor but also increases the availability of the systems.
Motor feeders capable of communicating with these soft starters
can be designed with just a few manual steps and accessory
parts.
The advantages of a soft starter are:
• Reduction of the mechanical load in the entire operating
mechanism
• Reduced load on the power supply network
■ Selection and ordering data
1) Just support, connection plug and power connector set are required to mount
the AS-Interface load feeder module onto the standard mounting rail adapter.
Detailed information on solid-state soft starters can be found in
