Industrial FCL-400 5-4 Split Core Current Transformer

The Industrial FCL-400 5-4 Split Core Current Transformer delivers a 400:5 A current ratio in a split-core design, allowing you to measure AC current by clamping around an existing conductor without disconnecting the circuit. Part of the FLEX-CORE line, this device combines a compact form factor with easy installation, making it suitable for panel mounting, electrical distributions, and energy-monitoring setups in industrial environments. Its split-core construction enables non-invasive installation, while the 400 A primary and 5 A secondary rating provides a standard current output that can be interfaced with meters, relays, or data loggers. The 400:5 A ratio supports accurate, scalable measurement across large loads, supporting applications such as load profiling, power monitoring, and protection schemes in commercial and industrial facilities. Clocking in as a robust solution for non-destructive current sensing, the FCL-400 5-4 is designed to integrate with existing electrical infrastructure to help quantify energy usage and identify inefficiencies.
