Current transformers specially designed to be installed above a switch
In installations that allow the power supply to be stopped to install transformers. Very useful to install in places where the exact nominal current range is not known. Each transformer has 3 ratio ranges by changing a connection cable and the chosen ratio in the measuring device.
Installation in confined spaces, utilizing the space above the circuit breakers and earth leakage protection In installations that allow the power supply to be shut down for the installation of transformers.
