6．Outline Drawing, Installation Dimension and Coil Diagram:( tolerance ± 0.5mm) 

7．Typical Application and Technical Parameters:

The sampling voltage is obtained directly by using a resistor.

The parameters are listed in table below.

● Notes:

a．In practical applications, the sampling resistor should be smaller than or equal to rated value given in table above in order to improve 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:

① Connect the primary winding of the current transformer in series with the measured current loop, and operate the secondary winding in near short-circuit mode.

② Do not allow the secondary winding of the current transformer to be open-circuited and do not install any fuse in the secondary circuit.
