Fairford Soft Starters XFE is capable of starting parallel-connected motors simultaneously provided each motor has similar characteristics and load. For such configurations the unit rating should be at least the sum of the current ratings of all the motors.

Alternatively, the Fairford Soft Starters XFE can start and stop motors sequentially using bypass contactors under the control of the programmable relay set as a ‘Top of Ramp’ relay. The dual setting feature allows for the control of motors with different start-up requirements. Details on multiple motor applications can obtained via your supplier.
