High-Performance YADA SCT24L Split-Core Current Transformer 50 A–300 A → 10 mA Output | Compact Design for Energy Monitoring & Metering

Product Overview

The YADA SCT24L is a split–core current transformer (CT) designed for accurate current sensing in power monitoring systems. Covering a wide primary current range of 50 A to 300 A, it outputs a precise 10 mA secondary current, making it ideal for energy management, sub-metering, industrial monitoring, and smart building applications. The split-core construction enables easy retrofitting into existing cable runs without disconnecting conductors, reducing installation downtime.
