This is a mini split-core current transformer, designed for energy metering applications. It features a compact design, making it one of the smallest in its class, with a 16mm inner hole diameter and 0.5 accuracy class. The transformer has a snap-fit structure that allows direct mounting on cables using nylon ties, enabling quick and easy installation without the need to disconnect power. It includes a built-in input coil and is fully enclosed, providing excellent mechanical strength, environmental resistance, and high voltage isolation for safe and reliable operation. Suitable for use with AC 220V and 380V power systems, it supports a measuring range of 0–100A and is ideal for split-core current sensing in energy metering devices.
