Product Description
The MSQ Series current transformer has been specially designed to facilitate their installation in new or already existing networks. They may be installed without opening any cable or busbar circuit. The connection of conventional CTs usually requires the interruption of the primary side current to pass cables or busbar through the transformer core to connect such cables to the primary terminals.
Key Features
- ● Two installation methods: Panel / Busbar.
- ● Wide inner window, allowing clamping of big cables or busbar.
- ● Wide range of sizes to accommodate all the existing installation.
- ● Primary current from 5A to 5000A.
