KECA 80 C Indoor Current Sensor Technical Data

This document describes ABB's AdvaSenseTM KECA 80 Cxxx series indoor current sensors, which use Rogowski coil technology without a ferromagnetic core for highly linear and accurate current measurement in medium voltage power systems. It details the sensor's parameters, combined metering and protection accuracy classes (0.5/5P400, 0.5/5P630, 0.5-A2/5P 85kA), and applications in UniGear ZS1 switchgear and OneFit retrofill designs.
