High sensitivity Zero sequence current transformer ZCT203
Zero phase current transformer which detects the difference between the currents flowing in a number of conductors. The current flowing to a load must equal the current flowing back from the load. If this is not the case, a potentially dangerous residual current will be flowing somewhere in the installation.
Wire lead type zero phase current transformers are easy integrated into standard PCB sub-assemblies that are compliant with IEC61008, IEC61009 and IEC62423 requirements.
