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.
