CT02 series Current transformer with DC immunity use Iron (Fe) base (80A)core low price high Accuracy , copper bar
Features:
1. With high permeability core, excellent linearity, excellent linear performance
2. It is applicable for working frequency 50-400Hz
3. With burnt-resistant ABS case and epoxy resin, current transformer can reach insulation resistance of 500VDC ≥100mΩ, electrical strength 3000VAC,1mA 60S.
4. Primary applies with copper bar, able to be directly installed to the button box, low load resistance, safety mounting.
For our current transformers, which are produced by using high permeability permalloy core or good quality laminated silicon steel core, inflammable epoxy resin and case with our high precision toroidal winding machine & current transformer testers, steady quality and reliable safety, are widely applied in electronic energy meter, power transducer, RTU, electronical monitoring meter, power factor compensator, digital meter, motor control, industrial control system, electrical meter equipment, etc.
