1. DESCRIPTION The DP 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 through the transformer core or to connect such cables to the primary terminals. The DP 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.
2. FEATURE Two built in fixing methods: Base; Busbar mounting Very easy to mounting. Wide inner window, allowing clamping of big cables or bus-bars. Wide range of sizes to accommodate all the existing installations. Primary current from 5A to 5000A.
