Indoor High Voltage Load Switch MCCB Structure Vacuum Load Break Switch
Overview
FN16A-12 Series switch for AC 50Hz, rated voltage of 10kV network, can be breaking the load current, overload current and closing short-circuit current. Combination of electrical short-circuit breaking current, especially for oil-free, no maintenance required and frequent operation places.
The innovative product design, small size, flexible installation, simple operation, with manual, electric two-function operation. With its operating mechanism CS6-1 type of CS or dedicated type, can also be directly manipulated in the back of the switch, you do not need to reprovision operating mechanism.
