CJ19 Changeover capacitor Ac contactor

The CJ19 series switching capacitor contactor is specially designed for efficient switching of low-voltage parallel capacitors and is an important part of 380V 50Hz reactive power compensation equipment. This series of contactors are equipped with a surge current suppression device, which effectively reduces the impact of closing surge current on the capacitor and ensures smooth and reliable operation. Despite their powerful switching capabilities, these contactors are small, lightweight and easy to install, making them a versatile choice for a variety of applications. These contactors are available in sizes ranging from 25A to 95A, offering a variety of options to meet different power compensation needs.

    Product Details

    Introduction

    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.

    Product Description

    Normal Running And Installation Conditions:
