KSO-303 SERIES COLLECTING CHAMBERS
Description
The KSO-303 series collecting chambers are designed for installation in the RU 6-10kV block boxes of modular buildings, indoor installation in capital buildings and substations with limited space.
The main distinctive feature of the KSO-303 series collecting chambers is the application of commutation devices which are installed transversally in relation to busbars within the chamber body.
