Detailed Product Description

*Summary

CJX1-630/820A Vacuum AC Contactor adopt Vacuum-blast contact block, it has small body and large capacity. Its operating current reach 630A/820A.The contact block has little abrasion and wont produce arc or switch gas. The design of its electro-magnetic system reach international advanced level, the system is designed to high voltage making and low voltage maintaining, so this equipment has the advantage of small operating current, no-noise and power saving. Comparing to the traditional 630A AC contactor, for example, when coil voltage is 220V and operating time is 8hours/day, one contactor would save power about 1200kwh per year, it can be widely used instead of 3TF68/69 series Ac contactor.

*Application

CJX1-630A Vacuum Ac contactor is suitable for frequency 50/60Hz, rated insulation voltage up to 1000V, rated operation current 630A and rated operating voltage 380V under AC-3 duty. It is mainly used for making/breaking electric circuit at a long distance&with thermal relay to compose a magnetic motor starter. It adopt the power saving circuit of AC/DC making and DC low-voltage maintaining.
