ZCT (Zero-phase Current Transformer)
                
                 
                
                  A sensor that detects leakage current
                
                
                
                  It is applied to the 
                  ICCB(IC-CPD)/of slow charging cables and wall charger, 
                  household charging devices, which detects
AC/DC
                  leakage current during 
charging to prevent secondary
                  
accidents such as electric shock, etc.
