Product Description

Main Application
   EVS160-630/EVS800-1600 serial vacuum contactor is applicable to the power system with 50/60HZ alternating current, rated operating voltage up to 1140V(2000V), rated operating current up to 1600A to switch-on or off the circuit at a long-distance, to start frequently and control alternating motor under and to form electromagnetic starter with other kinds of protective device. EVS800-1600 is applicable to AC-1, AC-2, FUNCTION CLASS.
   Because vacuum contactor has more advantages than the traditional air AC contactor for its longer lifetime, higher reliability, and the auxiliary switches that can combine electrical device, therefore, it can completely take the place of the traditional air AC contactor. Its economical characteristic can be displayed better in the application for the field of mine, metallurgical, chemical and petrolic industry, and heavy industries department.
