Full Voltage Starter: A contactor is used to control the pump motor. A thermal overload is used to inhibit the motor in the event
of an overload condition.
Soft Start: A soft start limits the in-rush current associated with a typical motor start-up. With the current limited, it allows
the ramp up to speed gradually. A soft start is an efficient way to keep your power factor in check as well as extend the life of your motor.
Motor current draw is monitored by the soft start and will shutdown in the event of an overload.
VFD (Variable frequency drive): A VFD has the benefits of a soft start as well the ability to vary the operating speed of the motor. Motor current
draw is monitored by the VFD and will shutdown in the event of an overload.
