The XFE Soft Starter is the choice where cost is an issue or if you need lighter start duty capability and overload protection than the QFE.

With exactly the same pedigree and underlying engineering as the QFE, the XFE has a range of ratings and options available such as use with an external bypass contactor and non-energy optimising or optimising depending on your application.

The easy-to-use keypad and high visibility LCD multi-character display are just two of the features which make this Soft Starter the ideal choice for most applications and places this unit way ahead of the competition.

Features and Benefits

Auto Set Up

Caters for the starting and stopping ramp profile for a specific application with no further adjustment needed, plus programming of all the relays, inputs and outputs etc.

Patented "Fairford System" of Energy Optimising

Improves partial load power factor (cos phi) saving energy, carbon emissions from generating source and cost on lightly loaded applications.

Manual Adjustment

Enables Soft Starter to be rapidly tailored to any application, saving time.

Smooth Step Less Acceleration of Motors to Full Speed with Reduction of Inrush Currents

Prevents or reduces breakages of belts, gears, chains, motor mountings and eliminates shock loading on equipment.

Unit Records History of Last 5 Trips

Assists in determining causes of any failure, saving on investigation time.

Adjustable Over Current "Shear Pin" Protection

Can significantly reduce the maintenance time in comprison to mechanical "Shear Pins", reducing down time.

Adjustable Overload

Protects the Soft Starter against damage due to overloads and therefore replacment or repair costs.

Six Button Keypad, 2 Line 32 Character LCD Display

Saves time programming and fault finding because it displays in English rather than short codes. Start/Stop capability, continuous display of motor phase current and control status - starting, stopping, full volts, current limitation, overload indication and fault indication.

Option of Modbus Comms or Remote Keypod Operation

Can be linked to a PLC for remote control using Modbus comms. Using the Remote Keypod can add versatility to allow one keypod to control more, up to eight units, saving on cost.

In The Delta Capability

Could allow a smaller unit to be used on an application, saving on cost.
