CSX Soft Starter

AuCom’s CSX soft starters provide greater control over the starting and stopping of three phase motors. There are two product ranges: the CSX for a simple soft start control device, or the CSXi for an advanced soft start system complete with motor protection.

The CSX range is a Timed Voltage Ramp system that provides soft start and soft stop functionality in a very compact frame.

The CSX is a Compact and cost Effective soft starter solution.
Simple operation and a built-in bypass function make the CSX series a pleasure to use with many benefits in a tidy package.

Compact Design

The CSX soft starter is a compact unit suitable for mounting in a switchboard or Motor Control Centre without the need for an external bypass contactor. At only 165 mm deep it is easy to mount in shallow switchboards.

For motors up to 60 A, soft starters can be mounted on a DIN-rail. Or the CSX may be mounted in a bank horizontally to use less space, often critical in certain switchboards.

Simple to use

CSX series soft starters are easy to use with as only three adjustments to be made to get started:

  • initial start time
  • start ramp time
  • soft stop ramp time

Adjustments are made using simple rotary switches. The CSXi soft starters allow more control over starts and stops with several adjustment controls.

Built-in Bypass function

CSX soft starters are equipped with integrated bypass function. The internal bypass function allow CSX starters to be easily installed into switchboards or motor control cubicles without need for extra ventilation or external bypass contactors.
