7.Typical Usage and Parameters:

The parameters are listed in the following table while the application is shown as right Fig.

Remarks:
a.In practical applications, the sampling resistor should be smaller than or equal to the rated value given in table above in order to improve the non-linearity and phase shift.
b.We can have it customer-made if required current ratio is not listed in the table above.

8.Attention:

• The primary of the current transformer must be connected in series with the loop of the measured current. The secondary should operate in a mode of near short circuit.
• The secondary of the current transformer is not allowed to be open circuit, Do Not install any fuse.
