Detailed Product Description

Because of its excellent performance and advanced technique, the vacuum arc chute is wildly used in breakers, and contactors etc. It features in energy saving, anti-fire, anti-explosion, small-volume, long life time, easy repair, reliable and no pollution. It is the update product of the old type. 
Our company has imported advanced technologies and key equipment from EAW company of Germany in 1990's. After the development and innovation, we have step into the huge scale producing. Guoguang vacuum arc chute's rated voltage covers 660V, 1. 14kv, 3. 6kv, 7. 2kv, 12kV, 40. 5kv; rated current covers 80A-4000A, the quality system matches requirements of ISO9001. We can supply varies of vacuum are chutes to customers. 
The series EVS160-630 of heavy task low-voltage vacuum contactor is produced with the technology and key equipment introduced from abroad by our company. This product has met IEC, VDE technical standards and reached the ninties international advanced level. 
This series of vacuum contactors have such advantages as high capabilities of switch-on and switch-off, long electrical and mechanical lifetimes and high operating reliability under the bad conditions. They are especially suitable for being used in the basic industries, metallurgical, petrolic, chemical industries, mine and wharf. It is applicable to the power system with 50Hz / 60Hz alternating current, rated operating voltage up to 1140V, rated operating current up to 630A to switch-on or off the circuit at a short or long-distance, to start frequently and control alternating motor under the heavy task and to form eletromagnetic starter with other kinds of protective devices.
