Heavy Task Low Voltage Vacuum Contactor Metallurgical Petrol Chemical Industrial

EVS160-630A Heavy Task Low-voltage Vacuum Contactor

    The series EVS 160-630 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. 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, 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.

                                                       Main Parameter
