LZZBJ9-10A, C Current Transformer
Product Functions
The LZZBJ9-10A/C series serves as a critical sensing and isolation component in 10kV power distribution networks. Its primary function is to accurately step down high primary currents (up to 1500A) to standardized, safe secondary levels (1A or 5A) for monitoring and control. Depending on the selected model variant (A or C), it provides precise signals for energy metering and billing (0.2S class) and/or general measurement (0.5 class), while simultaneously delivering stable outputs for circuit protection (10P class) via integrated dual-winding or triple-winding designs.
Applicable Environment
This product line is engineered for indoor installations within controlled environments. It is ideally suited for integration into 10kV metal-clad switchgear, ring main units (RMUs), compact substations, and indoor distribution panels. Typical applications include industrial plant electrical rooms, commercial building power distribution centers, data center power infrastructure, and renewable energy grid-connection points where equipment is protected from direct weather exposure. It is a core component for safe and efficient power management in medium-voltage indoor switchgear.
Product Highlights
