Description

 

The MCJ11-1.14 vacuum contactor is designed for frequent switching of electrical loads in three-phase alternating current networks with voltages up to 1140V and a frequency of 50-60Hz, carrying out currents both under normal conditions and under conditions of operating overloads.

Rated voltage, kV: 1,14

The greatest working voltage, kV: 1,14

Rated current, A: 125, 160

Number of Poles: 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.
