6．Outline Drawing, Installation Dimension and Coil Diagram: (tolerance±1mm)

① Outline drawing and installation dimensions are shown in Figure 1:

② The coil diagram is shown in Figure 2:

● Note: Each product is supplied with two bottom plate feet, one busbar foot and screws for fixing the busbar. See below for installation instructions.

③ Installation Notes:

● When fixing to the bottom plate: take two feet ( supplied with the product ) and insert them into the foot sockets on the bottom plate as shown in Figure 3. The center distance of the installation holes is 60 × 53 ; the diameter of the mounting holes of the feet is Φ 5 ; the transformer can be fixed on the bottom plate with M5 screws; (note: there are also 6 8 hole distance mounting plates optional)

● When fixing to the busbar: take a foot with M5 holes ( supplied with the product ) and insert it into the busbar foot slot as shown in Figure 3. The center distance of the M5 holes is 59 , and the transformer can be fixed on the busbar with M5 screws.

7. Typical Application and Performance Parameters:

See the table below for performance parameters when applied as shown in Figure 4

● Notes:

a. In practical applications, the sampling resistance should be less than or equal to the rated value given in the above table, which will improve the nonlinearity and phase shift;

b. If the conversion ratio required by the user is different from the above, it can be customized according to the user's requirements.

8. Attention:

① The primary of the current transformer should be connected in series with the current circuit under test, and the secondary should operate in approximate short-circuit mode.

② The secondary circuit of the current transformer must not be allowed to open circuit during operation, so please do not install any fuse.
