Product Description

FZN25 vacuum load switch and combination electrical appliance, suitable for three-phase AC 50Hz loop network or terminal power supply and industrial electrical equipment, used for load control and short circuit protection. The load switch separates and closes the load, closed-loop current, no-load transformer, and cable charging current. The combination electrical appliance can be disconnected to any current up to the rated short-circuit current. Adopting direct action isolation fracture and vacuum arc chamber linkage. Equipped with manual and electric functions.
The unique transmission structure design of FZN25 allows the arc extinguishing chamber to withstand high voltage only at the moment of closing and breaking, resulting in small volume and light weight.
FZN25 can achieve one-time operation of isolating and extinguishing chamber fractures.
FNZ25 has a grounding valve that is interlocked with the grounding switch between the static contact and the moving contact conductive cylinder, ensuring safety and facilitating maintenance.
