General Electric 631X28 Current Transformer

General Electric 631X28 Current Transformer with a 150:5 primary-to-secondary ratio delivers a precise step-down for high currents in electrical panels. This Type JCH-O CT carries a Class 0.8 kV insulation rating, and the model data includes 25-400 as part of its specification. In typical electrical installations, CTs like this GE unit provide a safe secondary current for metering, relays, and protection circuits, enabling accurate measurement and monitoring of load conditions. The 631X28 designation identifies this unit within GE's current transformer lineup, aligning it with equipment and instrumentation that require a 150:5 CT in industrial or commercial systems.
