    Description


    The ESCT-B Series current transformer has been specially designed to facilitate their installation in new or already existing net works, They may be installed without opening any cable or bus-bar circuit. The connection of conventional CTs usually requires the interruption of the primary side circuit to pass cables or bur-bars thought the transformer core or to connect such cables to the primary terminals. The ESCT-B series transformers core may be easily opened and they may be installed and connected without any supply interruption. Thus saving time and the installation costs.
