Pin-type zero sequence current transformer



Pin-type zero-phase current transformer:

A zero-phase current transformer for detecting the difference between currents flowing in multiple conductors. The current flowing to the load must be equal to the current flowing back from the load. If this is not the case, then the potentially dangerous residual current will flow somewhere in the device.

Lead-type zero-phase current transformers can be easily integrated into standard printed circuit board assemblies that comply with IEC61008, IEC61009 and IEC62423.
