FZN25-12 series indoor HV load switch is the indoor appliance of three-phase AC 50Hz, rated voltage 12KV, it is used in distribution substation and transformer substation for protecting and controlling electric appliance as well as switching on/off load current, closed-loop current, idling voltage transformer and cable's charging current. This product owns manual and electric-motor operation structure so as to meet three remote-control demand of power system.

FZRN25-12 series high voltage vacuum load switch-fuse combinations is one indoor device of three-phase AC 50Hz and rated volt being 12kv, it is applied to transformer substation and mining enterprise substation etc, to be used for load controlling and short protection, the equipped earthing switch could, the operation mechanism can be worked in manual and electric way, which can realize three-remote-control demand for power system.

FZRN25-12 series load switch and combination appliance are applied to three phases ring net and terminal power-supply urban power distribution station and industrial/civil equipment, to be used for load controlling and short protection. For combination apparatus is more reliable and economical than circuit breaker in respect of protecting volt transformer or other electrical apparatuses, so this product is especially suitable for ring net, bi-radial power supply unit and box type transformer substation etc.
