Application
CKJ5 series AC Vacuum Contactor is designed for long-distance making and breaking in circuit, frequency starting and controlling AC motor in the power system with AC 50 Hz-60Hz, rated operating voltage to 1140V. It also can be formed with thermal relay and all kinds of protection apparatus, as electromagnetic starter, especially applies to explosion electromagnetic starter and all sorts of power control equipment. It may apply to the department of mine, metallurgy, petroleum, chemical industry, power, communication transportation and so on.
The contactor conforms to IEC 60947-4-1,GB/T 14048.4 and JB/TN 7122 standard,the main performance indicators have reached the international level.
"Y"means this product has coil operation mechanism type and permanent magnet operation mechanism type.Coil operation mechanism type is normally used.Customers can choose the suitable type according to the application.
