Ckj5 Series 380/1140V Vacuum AC Contactor of Induction Voltage Regulator for Transformer

Product Description

Product DescriptionCKJ5 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.Product Parameters
Product technical parameters and external dimensions Product structure featuresVacuum contactors utilize vacuum bottle encapsulated contacts to suppress the arc. This arc suppression allows the contacts to be much smaller and use less space than air break contacts at higher currents. As the contacts are encapsulated, vacuum contactors are used fairly extensively in dirty applications, such as mining.
Vacuum contactors are only applicable for use in AC systems. The AC arc generated upon opening of the contacts will self-extinguish at the zero-crossing of the current waveform, with the vacuum preventing a re-strike of the arc across the open contacts. Vacuum contactors are therefore very efficient at disrupting the energy of an electric arc and are used when relatively fast switching is required, as the maximum break time is determined by the periodicity of the AC waveform.
