Overview

The ABB CMS-102CA is an 18mm solid-core current sensor with a 20A measurement range, designed for industrial current monitoring in control systems. Part of ABB’s CMS-100 series, this sensor delivers TRMS AC (50/60 Hz) and DC current measurements with ±1% AC accuracy at +25°C and a crest factor of ≤6. It features a 5000Hz sampling rate, 0.01A resolution, and a typical settling time of 0.25 seconds. The sensor operates from -25°C to +70°C and meets DIN EN 61010-1 and UL508 standards. Its compact 17.4 x 41.0 x 26.5mm dimensions allow DIN-rail or cable mounting, making it ideal for motor drives, power distribution units, and renewable energy systems. Compatible with CMS-600 and CMS-700 control units via Modbus RTU (RS485).
