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.
Soft Start / Soft Stop
Multiple starting curves adaptable to different loads
Multiple parameters in one soft starter, accommodating a wide range of power for different motors
Full functional testing in the field with low-voltage motors
Comprehensive motor protections even in bypass mode
Isolation between high voltage and low voltage circuit
Adaptable to various load conditions: large inertia load start, frequently changing load start, generator power supply start, synchronous motor start
3Ph medium voltage squirrel cage
3Ph Synchronous Motor
3kV, 3.3kV, 6kV, 6.6kV, 10kV, 11kV, 13.8kV AC ( ±10%)
