CJ19 series switched capacitor contactors are specially designed for efficient switching of low-voltage parallel capacitors and are widely used in reactive power compensation equipment operating at 380V AC 50Hz. The surge current system integrated in the contactor effectively reduces the impact on the capacitor, minimizes switching excessive value during circuit break, and ensures smooth and reliable operation. In addition, these contactors can replace a switching device consisting of one contactor and three current-limiting reactors, providing a compact, lightweight, and convenient alternative with high-capacity switching capabilities.
In addition, this series of contactors complies with the IEC60947-4-1 standard to ensure compliance with industry regulations and standards. CJ19 series AC contactor is suitable for circuits with rated voltage up to 400V AC 50Hz or 60Hz. It is specially designed for use in combination with low-voltage reactive power compensator or to cut off low-voltage parallel capacitors. The integrated suppression device effectively reduces the impact of transient surge current during startup and overvoltage during shutdown, further enhancing the safety and reliability of the equipment.
