specification is 200A/5A, When the input current is 200A, S1 and S2
as the output, S1 is connected to S3 in parallel, and S2 is
connected to S4 in parallel. When the input current is 400A, S1 and
S4 as output, S2 and S3 are connected in series.Installation
instructionsWarning: Please use professional and appropriate
protective equipment to prevent electric shock and ensure
safety.Installation stepsStep1. Before installing, ensure that the
circuit is in the state of power failure, or live installation
operation, professional personnel are required.Step 2. Open the
protective cover of current transformer, connect the wire with the
terminal output of the current transformer and connect it to the
port of the measuring equipment, and ensure the circuit is closed.
See Figure 1.Step 3. Open the transformer latch and prepare for
installation. See Figure 2.Step 4. Place the cable inside the hole
of current transformer. Ensure that the current direction of the
cable is consistent with the arrow on the current transformer. Lock
the latch again, and fix the cable with the nylon ties to hook both
ends of the transformer to prevent sliding. See Figure 3.
