GENERAL SPECIFICATIONS
BYA type switch-disconnectors provide "switching - disconnecting" features.
Disconnector main circuit contacts are in an epoxy cast body, which is filled with 1.5 bar SF6 gas and guaranteed for lifetime gas tightness.
Main circuit contacts can only be in one of the two positions "Open" and "Closed".
The grounding disconnector is located outside the epoxy body and its position can be observed directly, safely and reliably by the user. There is a mechanical interlocking mechanism that ensures safe operation between the grounding disconnector and the main circuit contacts.
The explosion-proof reliability of the gas-filled epoxy body is ensured by the safety membrane on the back.
There are auxiliary contact options that specify the positions of the main circuit contacts and the earthing switch.
The control mechanism can be installed manually using a lever or optionally with a motor. The installed mechanism has accumulated energy for closing and opening.
Closing and opening operations can be done with close buttons or remotely with coils.
Tripping system can be applied with fuse throwing pin for protection purposes.
Mechanical lock system options with keys that can be used for different purposes can be made.
