Why Choose the ABB CMS-201CA 80 A Current Sensor?
The ABB CMS-201CA is a compact 80 A TRMS solid-core current sensor designed for detailed branch-circuit measurement within ABB InSite energy-monitoring systems. Its 25 mm solid-core format and universal cable-mounting design make it suitable for monitoring individual conductors independently of the brand or type of protective and switching device used in the final circuit.
The CMS-201CA measures TRMS AC and DC currents, supporting instantaneous, minimum, maximum and hold values when used within the compatible monitoring system. With current measurement accuracy of ≤±0.5% full scale, the closed-core sensor provides dependable circuit-level measurement while offering good resistance to electromagnetic influences from adjacent final circuits.
The sensor communicates with compatible ABB InSite SCU100 and SCU200 control units through the InSite bus using a 4-pole flat cable. Its cable-mounting arrangement can be secured with cable ties, providing a flexible solution for energy monitoring, load supervision and circuit-level electrical analysis in distribution boards and other electrical installations.

Flexible Circuit-Level Current Monitoring
The ABB CMS-201CA enables detailed monitoring of individual electrical circuits rather than limiting measurement to the total incoming supply. Its 80 A rating, TRMS measurement technology and ability to measure both AC and DC currents make it suitable for a broad range of branch-circuit and load-monitoring applications.
Universal cable mounting allows the sensor to be installed independently of the make of the protective or switching device, while the InSite bus provides a streamlined connection to compatible ABB control units. Multiple CMS sensors can therefore be incorporated into an energy-monitoring system to improve visibility of individual loads, support energy-efficiency analysis and assist with electrical-system supervision.
