3 phase current transformer metal shielding case 120A anti-magnetic
mini CT
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
