Nancal Electric NC3S Series
Medium Voltage Soft Starter
NC3S Series Medium Voltage Soft Starter helps users reduce starting current of the high-power motor, and protect the other equipment affected by system voltage drops.
NC 3S SST is a solid-state soft starter which is to change the motor's voltage gradually (or reduces the starting current) by controlling the conduct Angle of the thyristors.
When the soft starter starts and finishes, the power is transferred to power frequency by the bypass contactor, and the motor continues running and is always protected. In addition to supplying complete units, we also offer soft starters as loose items, including power cells, contactors, control boxes and others for customers who have the capability to assemble them into cabinets independently.
