  • ABB Library - Disconnecting Circuit Breakers

    The change of design principle has enabled the integration of the disconnecting function with the CB, thereby creating a new apparatus called a disconnecting CB (DCB). Since the primary contacts for DCBs are in an SF6 protected environment, free from pollution, the disconnecting function is highly reliable and the maintenance interval is
