Description

General:
FN5-12\ FN5-12RD \FN5-12R Series Indoor Alternative Current High Voltage Load switch is suitable in 50Hz,
10kV alternative current, power supply net for breaking load current and closing short circuit current. Load
switch with fuse can close and open short circuit current for protection.
Specified CS manual operative mechanism or CS6-1 manual operative mechanism could be matched with
this kind of series switches.
