JUK (BH) Window Type Current Transformer is designed for current measurement and monitoring in low-voltage power distribution systems. As a series product, it is suitable for a wide range of applications in electrical panels, switchgear, and control cabinets.The transformer adopts a window-type (solid core) structure, allowing the primary conductor or busbar to pass directly through the center opening without electrical connection. This design simplifies installation, improves operational safety, and ensures stable performance during long-term operation.The JUK (BH) series supports multiple primary current ratings, enabling flexible selection according to different load conditions. Standard secondary current outputs of 5A or 1A are available, making the transformer compatible with most energy meters, protection relays, and monitoring instruments.Different accuracy classes can be provided to meet measurement and monitoring requirements in various applications. The transformer features reliable insulation performance, stable electrical characteristics, and low power loss, ensuring accurate current transformation under continuous operation.With clear terminal markings (S1 / S2) and a compact mechanical design, the JUK (BH) current transformer is easy to install and maintain. It is widely used in residential, commercial, and industrial low-voltage power distribution systems for energy measurement, power monitoring, and electrical protection.
