FN16A Vacuum Load Break Switch with Disconnector 12kV 24kV 40.5kV
description
FN16A indoor AC M.V Vacuum load break switch 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. This switch applied for the 50/60Hz, 6-24kV Power distribution system. It can break on load current, and fuse combination can break the over load current and short circuit current. Load break switch with-fuse combinations are also used for protecting over load of transformer and avoiding short-circuit current.
