AC Contactor

Features of CKJ11 Series vacuum contactors: Vacuum contactors are full closed product adopting new technology, which have the characteristics of high operating voltage, small size, stability, long life, reliability, low pick-up power, low circuit resistance, easier maintenance and so on comparing with the traditional CKJ5 contactors. CKJ11 contactors have got the national patent.
CHV series AC Contactors are suitable for following making and breaking electric power system: AC 50Hz, 12kv or below main circuit working voltage level, 630A or below working current level, such as frequent operating and control AC electric motor and magnetic starter. They are widely used in electric power system, petroleum, chemical industry, coal mining, metallurgy and electrified railway and other fields.
Features of CKJ5 contactors: Vacuum contactors use vacuum interrupter as switching elements, the main circuit moveable and stationary contacts are sealed in the vacuum where the atmospheric pressure is lower than 1×10-2 Pa. Vacuum medium has good isolation and arc extinguishing ability, so the vacuum contactor is characterized as high isolation voltage, small contact stroke, low contact wear, long life and so on.
Features of CKG4 ac contactors: Extremely strong capacity of making and breaking, long electric life, safety and reliability, low noise, easier installation and maintenance.
Features of JCZ5  ac contactors: Small size, light weight, easier to use and maintain.
