FZN16-12 indoor high-voltage vacuum load switch|Hongtuo Transformer Co., Ltd

summary

FZN16-12 indoor AC high-voltage load switch-fuse combination appliance (hereinafter referred to as "series switch") is designed and developed by our factory. The performance meets the requirements of GB3804-90 "3-63KV AC High-voltage Load Switch" and IEC420 "AC High-voltage Load Switch-Fuse Combinations" (1990) and national standards (draft for approval). It has the advantages of safe and reliable breaking, long electrical life, frequent operation, basically no maintenance when breaking and transferring current, and obvious isolation of fractures. The load switch-fuse combination device also has the function of protecting the transformer from overload and preventing the equipment from running out of phase.

purpose

FZN16-12 series switch is applicable to the power grid with rated voltage of 6-12KV three-phase AC 50Hz, and is used for breaking load current, overload current and short circuit current, especially suitable for places without oil, maintenance and frequent operation requirements. This product can be used with CS6 - I operating mechanism and CS □ manual operating mechanism.
