Split-Core Current Transformer

OM-ACM-A200/100

Single-phase version and three-phase version

The Split-Core Current Transformer is a high-precision measuring device specifically designed for the power system. It can accurately measure current and is widely used in various fields such as electric energy metering, protection control, and fault detection. The transformer adopts advanced electromagnetic induction principles to ensure the stability and reliability of the measurement results. The product is available in two versions: single-phase and three-phase. The single-phase version is used for measuring single-phase current, while the three-phase version is for measuring three-phase current.
