Why Choose the ABB CMS-201DR 80 A DIN-Rail Current Sensor?
The ABB CMS-201DR is a compact and accurate solid-core current sensor designed for branch-circuit monitoring and energy-management applications. As part of the ABB CMS Circuit Monitoring System, this 25 mm sensor measures AC and DC currents using True RMS technology and provides detailed current data for compatible ABB InSite energy-monitoring systems.
Designed for universal DIN-rail mounting, the CMS-201DR can be used independently of the manufacturer of the protective or switching device installed in the monitored final circuit. Its closed solid-core construction provides high measurement accuracy and reduced sensitivity to electromagnetic influences from adjacent circuits, making it well suited to high-density electrical distribution equipment.
With an 80 A rated primary current, 15 mm conductor bore, 0.5% full-scale accuracy and an InSite bus flat-cable interface, the CMS-201DR provides dependable circuit-level monitoring with straightforward system integration. ABB order code 2CCA880133R0001 identifies this 25 mm DIN-rail-mounted CMS sensor.
