Description
Vacuum contactor MCJ30-3.3stationary type, three-pole — designed for frequent switching of electrical loads in three-phase alternating current networks with voltage up to 1140V at a frequency of 50-60Hz, conducting current under normal conditions and under conditions of operating overloads.
Rated voltage, kV: 3,0
The greatest working voltage, kV: 3,3
Rated current, A: 200, 350, 400
Number of Poles: 3 (Three Pole)
Vacuum contactors are installed in starters, stations and control units of asynchronous motors with squirrel-cage and phase rotors, in remote control systems of drives, control transformers and capacitive batteries. Due to the lack of an electric arc, it has safety and reliability characteristics, low noise level, low maintenance design, as well as small size.
