KECA 80 C85 Indoor Current Sensor Datasheet

This document describes the ABB AdvaSenseTM KECA 80 C85 indoor current sensor, a Rogowski coil-based device for current measurement in medium and low voltage switchgear. It highlights the sensor's linear, coreless design, which enables combined metering and protection accuracy classes (0.5/5P630 or 0.5-A2/5P 85kA) over a wide dynamic range, from 5% of rated primary current up to 85 kA.
