Yfn5-12r (T) D/125-31.5-Fuse Combination Unit Hv Load Break Switch
Basic Info
Model No.: YFN5-12R(T)D/125-31.5
Product Description
Model NO.: YFN5-12R(T)D/125-31.5 Structure: Fuse Pole: 3 Number of Switch: Multi Control Switch Installation: Indoor High Voltage Origin: Jiangyin Yunfeng, China Function: Industry Usage: Control Switch Rated Continuous Current: Max.Rated Current of Fuse Equipped:125A Certification: SGS, ISO9001, CE Trademark: YF Product Overview
YFN5(FN5)-12 series indoor AC HV load gas-production load switch and fuse combination unit is mainly applied in AC 12kV network for breaking the rated load current and making the short-circuit current. The performance shall meet the requirements of the national standards GB 3804-2004 High-voltage alternating-current switches for rated voltage above 3.6kV and less than 40.5kV and GB 16926-2009 High-voltage alternating current switch-fuse combinations. The fuse combination unit can break the short-circuit current and has the function of single-phase fuse three-phase tripping and breaking. It is the ideal selection for protecting the line, equipment and transformer.The series load switch has features of small size, light weight, simple and reasonable structure,small operating force, reliable performance and convenient maintenance,ect. It can be mounted on the wall or intalled in the HV switchgear and it is a type of HV load switch with advantageous cost performance.
