Summary
FN16A-12D/630 indoor AC H.V Vacuum load break switch and FN16A-12RD/200-31.5 load switch-fuse combination are developed by our company The products follow GB3804-90 3-62KV AC H.V load switch and IEC62271<AC H.V. indoor load break switch-fuse combinations>(2002 edition). These switches are small volume, beautiful appearances, flexible installation, and easy operation.
Load break switch with-fuse combinations are also used for protecting over load of transformer and avoiding short-circuit current.

Main Application
FN16A-12D/load switch and FN16A-12RD/200-31.5 switch-fuse combination are suitable for the power systems with AC 50Hz rated voltage 6-10kv. This switch is suitable for the oil less, less repair and frequent operating equipment.
This switch can match with CS6-1 Operating mechanism; the operator can directly operate on the switch.
The FN16A-12-J switch can operate manually (manual handle) and automatically (motor).
Service condition (Applying ambient conditions)
a.The ambient air temperature Max:+40oC ’Min:-25oC
b.The relative humidity:monthly average ≤ 90% daily average ≤ 95%
c.The altiude does ot exceed 1000m
d.The ambient don’t have corroder and the flammability gas.Etc
e.The working situation without frequent violent
