3 phase current transformer electricity meters use metal shielding CT with cross holes standard type
Suitable for high precision, small phase error requirments of three-phase electric energy meters
More space in the meter can be saved with combined current transformer
Linear output current, high precision
Encapsulated with epoxy resion,with high insulation ability
It accords with IEC60044-1 0.05 class, 0.1 class, 0.2 class
