Why Choose the ABB CMS-101PS 40 A Current Sensor?
The ABB CMS-101PS is a compact 40 A solid-core current sensor designed for branch-circuit measurement within ABB energy and circuit monitoring systems. With its 18 mm format, the sensor is designed for integration with System pro M compact and SMISSLINE installation devices with twin terminals, enabling individual circuits to be monitored without requiring conventional bulky current transformers.
The CMS-101PS provides a 0.1–40 A measuring range and measures TRMS AC and DC currents with current accuracy of ≤±0.5% full scale. Its solid-core construction provides accurate current measurement while offering good immunity to electromagnetic influences from neighbouring final circuits.
Measurement information is transmitted through the InSite bus using a 4-pole flat cable to the associated ABB monitoring control unit. The compact sensor therefore provides a practical building block for detailed circuit-level energy monitoring in distribution boards, commercial buildings, industrial installations and other applications where visibility of individual electrical loads is required.

Compact Circuit-Level Current Monitoring
The ABB CMS-101PS allows individual branch circuits to be monitored in a compact electrical distribution assembly. Its small solid-core design fits around the monitored conductor and measures current from 0.1 A up to 40 A, allowing the monitoring system to provide detailed information about the electrical load on individual circuits rather than only measuring total incoming consumption.
Multiple CMS sensors can form part of a wider ABB monitoring installation, with measured values transmitted through the flat-cable InSite bus to the associated control unit. This distributed measurement architecture supports energy-efficiency analysis, load monitoring and improved visibility of electrical consumption while minimising the space required inside the distribution board.
Typical Applications
- Branch-circuit current monitoring.
- Commercial building energy-management systems.
- Industrial electrical distribution boards.
- System pro M compact installations.
- SMISSLINE electrical distribution systems.
- Energy-consumption analysis at circuit level.
