Product Features Cap for Connector Protective cap for connectors on either side of the CT ensures that the terminal is well covered from external entities. The cap also contains sealing. Side Mounting Provision CBCT can be mounted both horizontally as well as vertically considering the practical challenges occurred while on site installation. Cable tie Clips Cable tie clips are located on the CT to ensure that the Busbar is centrally aligned so as to get absolute output. The Cable tie clip should be ordered separately Vertical Cable Tie Mounting Vertical mounting is basically provided in all...
