Product Description

Product Description

Load Break Switch
The FZN25 and FZRN25 vacuum load switches and composite devices suit three-phase AC 50Hz ring networks or terminal power supplies and industrial electrical gear. Ideal for load control and short circuit protection, these switches manage closed loop currents, no-load transformers, and cable charging currents. The composite device can interrupt any current up to the rated short circuit current.
Features a straight move or isolating fracture linked with a vacuum interrupter. Equipped
with both manual and electric operational capabilities.
The FZN25, FZRN25 boast a unique transmission structure design, with the arc
extinguish chamber enduring voltage during operation. Compact and cost-effective.
The FZN25, FZRN25 can achieve isolation fracture and arc extinguish chamber fracture
in a single operation.
These models feature a grounding switch with a mutual linkage grounding valve between
the static contact and movable conductive cylinder, ensuring safety and ease of
maintenance.
