Product Description
FNl6A-12 series switch is suitable for AC 50Hz, rated voltage 10kV network, especially for oil-free, maintenance and frequent operation places to break load current, overload current and close short-circuit current. The combined electric equipment breaks short-circuit current. It can be controlled through CS6-1 operating mechanism or specialized CS operating mechanism or directly at the back of switch without operating mechanism.


1. All-assembled switch and combined equipment has small dimension and compact structure

2. Both manual and electric operating mechanism with small operating force

3. Reliable mechanical interlock prevents mal-operation

4. Clearly visible clearance

5. Apply air compression arc extinguishing with stable performance and reliable, safe operation
6. The combined electric equipment has open-phase protection function
