Why Choose the ABB CMS-100DR 80A Current Sensor?
The ABB CMS-100DR, order code 2CCA880128R0001, is a compact 80 A closed-core current sensor designed for circuit-level electrical monitoring within ABB InSite Energy Management Systems. As part of the ABB CMS current sensor range, it combines accurate TRMS measurement with universal DIN-rail mounting for flexible installation in commercial and industrial electrical distribution systems.
The CMS-100DR measures AC and DC current across a range of 0.1–80 A and provides current accuracy of ≤±0.5% of full scale. Its solid-core construction offers high measurement accuracy and good immunity to electromagnetic influences from neighbouring final circuits, supporting dependable load monitoring and energy management.
Designed as an 18 mm universally usable DIN-rail sensor, the CMS-100DR can be installed independently of the manufacturer of the associated protective or switching device. Measured values are transmitted through the 4-pole InSite bus flat cable to a compatible ABB InSite control unit, making the sensor suitable for scalable multi-circuit monitoring installations.

Universal DIN-Rail Circuit Monitoring
The ABB CMS-100DR enables individual electrical circuits to be monitored within a centralised energy management system without tying the sensor installation to a particular protective-device manufacturer. Its DIN-rail mounting arrangement makes it particularly useful where a flexible monitoring architecture is required for existing or newly designed electrical distribution boards.
By measuring TRMS AC and DC current and transmitting the resulting data through the ABB InSite bus, the CMS-100DR supports detailed analysis of electrical loads and circuit behaviour. Multiple CMS sensors can be incorporated into a compatible ABB InSite installation, providing scalable circuit-level visibility for energy management, load analysis and electrical distribution monitoring.
