FKN12-12D/630-20 indoor AC high-voltage load switch fuse combination appliance, also known as FN-12D load switch, has a rated voltage of 12kV and a rated frequency of 50Hz. This innovative device is designed for distributing combined load current, closed loop current, no-load transformer, cable charging current and combined short-circuit current. It is worth noting that the load switch is equipped with a grounding switch, allowing it to effectively withstand short-circuit currents.
In addition, FKRN12-12D/125-31.5 AC high-voltage load switch fuse combination appliance, referred to as FKRN12-12(D) combination appliance, is an excellent fusion of FKRN12-12D load switch and S□LAJ. -12 (XRNT-10) high-voltage current-limiting indoor high-voltage switchgear and fuse combination. This combination appliance is capable of breaking any current up to short circuit current. The load switch is responsible for breaking the operating current, while the fuse is designed to break the current, jointly breaking any current between the operating current and the complete short-circuit current. In addition, the fuse facilitates the opening of the load switch through its impact force.
The application scope of FKN12-12D load switch and FKRN12-12D combination appliance is mainly focused on load control and short-circuit protection in urban power distribution stations and industrial electrical equipment powered by three-phase ring networks or terminals. These combination appliances are preferred over circuit breakers because they offer greater reliability in protecting electrical equipment such as transformers. They are particularly suitable for ring networks, radiant generator sets and box-type substations.
In short, the FKN12-12D/630-20 indoor AC high-voltage load switch fuse combination appliance and its FKRN12-12D/125-31.5 counterpart represent a major advancement in high-voltage switch technology. Their rugged design and versatile functionality make them indispensable for ensuring efficient and reliable power distribution and protection in a variety of industrial and urban environments.
