Nanocrystalline core  is the best material for zero sequence CT in a RCCB(residual current circuit breaker) core. RCCB is designed to disconnect the circuit if there is a leakage current. It is critically important in protecting circuit safety in both residential and industrial use. It can be classified into electronic type, electromagnetic type(DC pulsating); A type, AC type, B type ,etc. Zero sequence CT core is a critical component inside.
 
 
Characteristics:
   a.  Very high permeability and output voltage
