12KV Indoor HV AC Vacuum Load Switch - Fuse Combination Apparatus
Overview
FN16A-12RD/200-31.5 Type combination units within FN16A-12 in
combination with a high-voltage load switch current limiting fuse
together the indoor high voltage switchgear, the upper end of the
fuse is fixed to the lower bracket of the vacuum interrupter, the
lower end is fixed to the seat by contacting the insulator, lower
bracket grounding switch and fuse together. Grounding switch and
disconnecting switch with mechanical interlock.It can break
load current,overload current and short circuit current.
Technical Parameters: Load switch - fuse combinations
