Split current transformers can be used for clamp meters, which can measure the current without cutting the wires. This open-close type of current transformers can be used for measurement devices or instruments. We provide different size of split-core current transformer, suited for different low voltage electrical devices. Our mini type split CTs have the advantage of compact size, low error, and linear performance. Some big split current transformers are suitable for heavy electric current measurements. The turns ratio and lead wire length can be specified by customers.
