Why Choose the ABB CMS-100CA 80 A Current Sensor?
The ABB CMS-100CA is a compact and highly accurate solid-core current sensor designed for branch-circuit monitoring and energy-management applications. As part of the ABB CMS Circuit Monitoring System, it measures AC and DC currents using True RMS technology and provides reliable current data for ABB InSite energy-monitoring systems.
Designed for universal cable mounting, the CMS-100CA features an 18 mm sensor format and an 80 A measurement range. The sensor can be secured using cable ties, allowing installation independently of the manufacturer or type of protective and switching equipment used in the monitored circuit. Its closed solid-core construction provides high measurement accuracy and strong immunity to electromagnetic influences from adjacent circuits.
With a measurement range of 0.1–80 A, current accuracy of ≤±0.5% full scale and communication through the ABB InSite flat-cable bus, the CMS-100CA is well suited to detailed circuit-level energy monitoring in distribution boards and electrical installations. ABB order code 2CCA880107R0001 identifies this 80 A cable-mounted sensor.

Accurate Circuit Monitoring for Energy Management
Current sensors such as the ABB CMS-100CA enable individual electrical circuits to be monitored without requiring large conventional current transformers. Detailed branch-level current measurement gives facility and energy-management systems greater visibility of individual loads, helping operators analyse consumption, identify unusual operating conditions and improve electrical-system efficiency.
The CMS-100CA transmits measured values through the ABB InSite flat-cable bus to a compatible control unit. Its compact solid-core construction, high measurement accuracy and universal cable mounting make it particularly useful in distribution boards where numerous individual circuits need to be monitored within limited installation space.
Typical Applications
- ABB InSite energy-management systems.
- Branch-circuit current monitoring.
- Electrical distribution boards and switchboards.
- Commercial building energy monitoring.
- Industrial electrical load monitoring.
- Data centre and infrastructure power monitoring.
- AC and DC circuit measurement.
- Energy-consumption and load analysis.
