Zero phase current transformer used for water heater ZCT541

small zero phase current transformer : High sensitivity and close to zero load shift

Excellent characteristics in temperature and balance

Small change of output voltage after large DC impulse

A variety of configuration and output characteristics
Used for leakage current detection



Zero phase current transformer used for water heater ZCT541


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.
