● Description: Each product is supplied with two bottom plate feet, two sets of busbar feet and fixing busbar screws. See below for installation instructions.

③ Installation instructions :

● When fixing to the bottom plate :

Take the two feet ( supplied with the product ) and insert them into the foot sockets on the bottom plate as shown in Figure 3 on the right. The center distance of the mounting holes is 68×44.7 ; the mounting hole diameter of the feet is Φ5.0 ; the transformer can be fixed on the bottom plate with M5 screws.

● When fixing on the busbar :

Insert the two feet with M5 holes (supplied with the product ) into the slot of the busbar feet 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:

When the sampling voltage is directly obtained by the resistance method ( as shown in Figure 4 ) , the performance parameters are shown in the table below .

8.Attention:

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

② Do not allow the secondary circuit of the current transformer to be open-circuited. Do not connect any fuse in the secondary loop.
