Remark: Two support legs to be fixed on bottom board, one support leg with screws are included in package along with every product.

Installation instruction

Mounted on bottom board:
Take two support legs (included in package along with the product) and insert them into the sockets as shown in Fig. below. The center distance between the mounting holes is 57x42.5; The diameter of the mounting hole for the support leg is Ø 5.0, and then use M5 screw to fix the current transformer on the bottom board.

Mounted on primary wire:
Take one support leg with M5 hole (included in package along with the product) and insert it into the socket as shown in Fig. below. The center distance between the M5 hole is 57; fix the current transformer on the primary wire with M5 screw.

7.Typical Usage and Parameters:

The parameters in this application as shown in the upper right Fig. are listed in table below:

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.
