Our CSXi series soft starters allow you greater control over the starting and stopping of three phase motors. The CSXi series is ideal for simple but also advanced applications, with motor protection in the power range from 7,5 to 110 kW.

The CSXi soft starter is a constant current system, complete with current measurement and control. In addition to soft start and soft stop, the CSXi provides a range of motor protection functions, including motor overload, phase loss and excess start time.

The CSXi also features a programmable relay.

Compact Design

The CSXi 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 the soft starter 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 integrate

With features such as dedicated output relays to control the upstream main contactor and power factor correction capacitors, CSXi soft starters are easy to integrate into complete moto control solution.
 

Protection

The CSXi has built-in thermal model motor overload protection. The motor current is continuously monitored and the expected temperature is calculated based on this monitored current. The user sets the Motor Trip Class, and the CSXi will trip when the calculated motor temperature reaches 105 %.

An external motor protection device is not required when using a CSXi soft starter.
 

Energy savings

CSXi soft starters are equipped with an internal bypass function to reduce operating costs. CSXi starters are 99,5 % efficient during run, produce no harmonics and are the most energy efficient solution for fixed speed applications with variable load..

In addition, different communication cards such as DeviceNet, Ethernet/IP, Modbus RTU, Modbus TCP, Profibus and Profinet can be used.
