Low Voltage Vacuum Contactor Unit For Metallurgical Petrol Chemical Industrial
Vacuum Contactor Unit Introduction
Vacuum Contactor Unit is suitable to cooperate with various protection devices to be installed as an explosion-proof electromagnetic starter. This product is developed by using vacuum connection technology, storage and other international advanced integrated circuits and microcomputer technology. It is especially suitable for frequent starting of electric motor and control of closing and breaking of electric furnace transformer; it is also widely used in high voltage capacitor reactive power compensation device, so it has high protection precision, accurate fault analysis, complete protection function, reliable protection action and intuitive parameter display. Optional standard analog signal transmission and other functions, widely used in petroleum, chemical, electric power, metallurgy, coal, light industry, textile and other industries.
The Vacuum Contactor Unit 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. 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.
Vacuum Contactor Unit are especially suitable for being used in the basic industries, metallurgical, petrol-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 electro-magnet starter with other kinds of protective devices.
