EVS160-630 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 Germany. 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. The EVS vacuum contactor is used for low voltage DC electromagnetical structure, and can be assembled into 1, 2, 3...to n poles. They are especially suitable for being used in the basic industries, metallurgical, petrolic, chemical industries, mine and wharf. Its applicable to the power system with 50Hz alternating current, rated operating voltage up to 1140V, rated operating current separate into 160A, 250A, 400A and 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 electromagnetic starter with other kinds of protective devices.
