The current transformer primary should be connected in series with the current loop to be measured. The primary should be close to the circuit short circuit.2. Current mutual inductance primary circuit is not allowed to open circuit, so please do not install fuse3. The open current transformer should be connected to the secondary circuit if it is charged, and then connected to the primary circuit.colour:Blue + blackMaterial:plasticPackage Contents:3 * Current TransformerOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
