CKJ20 series vacuum contactor is suitable for AC 50Hz, rated working voltage to 2kV, rated working current to 800A circuit, for long-distance connection and breaking circuits, and can be combined with appropriate thermal overload relay or electronic protector and other related protection devices to form a vacuum electromagnetic starter. Among them, the permanent magnet model is the switch of the low-voltage prepaid metering box.

CKJ3 series is a high-current series, suitable for AC 50Hz-60Hz, rated voltage up to 1140V, up to 2kV. Control circuits with rated currents up to 800-1000-1250A. It is used for making and breaking circuits on and off long distances and for frequently starting AC motors.

ERCKG3 series AC high-voltage vacuum contactor (hereinafter referred to as: contactor) is suitable for AC 50-60Hz, the rated working voltage of the main circuit is 7.2kV, and the rated current is below 630A.

This product is a 12kV model derived from the ERCKG3-7.2kV model. This product is widely used in indoor devices used in power systems with AC 50Hz, rated operating voltage of 12kV, and rated working current up to 630A. It is used to frequently break and close the load circuit of AC high-voltage motors and transformers. At present, many domestic vacuum contactor manufacturers have made this model their flagship product. This product has a clear structure and is easy to debug, maintain and install.

ERJCZ8 series outdoor high-voltage vacuum contactor is suitable for AC 50Hz, rated working voltage to 1140V, rated working power 630A power network, for direct or long-distance connection and disconnection of the main circuit. Because the main contact works in a high vacuum environment, it has the advantages of no exposed arc, small size, light weight, long service life and long maintenance cycle, and is especially suitable for forming various street lamp controllers and working in oil fields, chemical industries and other occasions.

ERJCZ6 series permanent magnet high-voltage vacuum contactor (hereinafter referred to as contactor) is suitable for AC 50Hz or 60Hz, the main circuit rated voltage of 40.5kV, the rated current of 1250A and below in the power system, for direct or long-distance connection and disconnection of the line. It is suitable for the need for three control electrical circuits, with high reliability, long life, less maintenance, safety and other characteristics, this contactor is equipped with AC and DC permanent magnet mechanism.
