Product Description

Place of Origin	China
	Zhejiang
Brand Name	Shengsu
Model Number	FZN25
Phase	Three
Frequency	50Hz

FZN25, JLFZRN25 vacuum load switches and combination devices are suitable for load control and short circuit protection in three-phase AC 50Hz ring networks or terminal power supply and indusrical electrical equipment. The load switches are used for load sharing, closed-loop current, no-load transformer and cable charging current. Combination electrical appliances can disconnect any current up to the rated short-circuit current. Adopting a direct action isolation fracture and a vacuum arc extinguishing chamber linkage, Equipped with manual and electric functions.
