FZN25-12D/T630-20 Indoor AC high voltage load-breaking switch is three-phase AC 50Hz, rated voltage 12kV indoor installation, which is suitable for using in industry and mining situation and so on enterprise substation and transformer substtion for protection and controlling the electrical facility, uses in Off and ON load current, closed loop current, idling transformer and cable charging current. It has manual and electrical motor operating mechanism that isadvantageous to realize three remote controls requirement of power system.
FZRN25-12D/TX-31.5 Indoor AC high Voltage Vacuum Load Switch-The fuse combination electric appliance is three-phase AC 50Hz, rated voltage 12kV indoor installment, which is suitable for load control and short-circuit protection using in industry and mining situation and so on enterprise substation and transformer substation. It is equiped with the earthing switch that may withstand short-circuit current The operating mechanism can be possible manual and electrically operated that is advantageous to realize three remote controls requirement of electrical power system.
FZN25-12D, FZRN25-12D load switch and combination electric appliance are suitable for load control and to short-circuit the protection in three-phase ring net or the terminal power supply urban district power distribution station and the industry consumer. Because the combined electric appliance has more reliable, econnomical protection function than circuit breaker electrical appliance equipment such as the transformer, especially for the ring net, double rdiation power supply unit and box type transformer substation.
