EVS-200 vacuum contactors

The vacuum contactor EVS200 is an electromechanically operated device determined for frequent switching of exclusively alternating current circuits with low voltage up to 1000V and high voltage of up to 1200V according to EN 60947-4-1 and IEC 470/74 with currents of up to 200A in the range of closing and breaking currents corresponding to AC4 category. This contactor is used particularly for switching of squirrel-cage and slip-ring motors. It is suitable for switching of resistance and mixed loads. 

Your benefits:

- high reliability 

- long lifetime -

- minimum maintenance demanded during its whole lifetime 

- high frequency of repeated switches 

- small size and low weight
