Yubang Electric Introduces Indoor High-pressure Vacuum Load Switch

ZFN21-12D/T630-20 indoor high-voltage vacuum load on the relationship of three-phase AC 50Hz indoor high-voltage switchgear, suitable for the rated voltage of 12kV distribution system. The switch has the ability to close, load, break load and overload current; it can also open and close no-load long lines, no-load transformers and capacitors.

ZFN21-12DR/T125-31.5 indoor high-voltage vacuum load switch fuse combination is a combination of the load switch and fuse, in addition to the above-mentioned functions also have a protection function.
