A single soft starter can be used to control multiple motors, either
in sequence or in parallel, provided the soft starter is correctly
selected for the application.
Motors in sequence
For two or more motors in sequence, the soft starter must be
capable of bearing the total start duty.
Installation requires additional wiring, plus separate overload
protection and line and bypass contactors for each motor. The ad-
ditional installation costs may be greater than the cost of individual
soft starters.
* This control method is complex and would require the use
of a PLC or smart relay.
Multiple motors: Can one soft starter be used
to control multiple motors?
