Soft starter contactor vacuum contactor CKG series for AC motor
1.Detail descriptionÂ
This series of vacuum contactors are suitable for the electricity network system 12kv below power network systems for installation of mechanical interlocking shaft between the two vacuum contactor can achieve mechanical interlock and interlock function, can also achieve electrical lockout.
Mainly used to enhance the electronic control circuit as the pros and cons of conversion, dynamic braking, the main line switch, frequent operation, have the advantage of long mechanical life, high reliability, low maintenance, excellent breaking performance. This series of vacuum contactor also can be used to control the high pressure air the pros and cons of conversion to a load and as a master switch.
