Spare Parts
AO VO "Electroapparat" is the sole manufacturer of the VVN and VVS series air circuit breakers used in power facilities across Russia and CIS countries. The original developer of these breakers, AO "NIIVA," has licensed all design documentation to Electroapparat. Consequently, for reliable performance and compatibility, it is recommended to purchase spare parts directly from Electroapparat, as parts from other suppliers may not meet technical standards and could lead to equipment failure.
