Why Choose the ABB CMS-200S8 160 A Current Sensor?
The ABB CMS-200S8 is a compact 160 A TRMS solid-core current sensor designed for detailed circuit-level current measurement within ABB energy-monitoring systems. Its 25 mm solid-core format is specifically designed for mounting on compatible ABB S800 high-performance circuit breakers with cage terminals, providing an integrated measurement solution for higher-current branch circuits.
The CMS-200S8 measures TRMS AC at 50/60 Hz and DC current across a range up to 160 A. AC current accuracy is ≤±0.5% at an ambient temperature of +25 °C, providing dependable measurement for load supervision, energy analysis and circuit-level electrical monitoring.
Its compact S800 mounting arrangement allows current measurement to be added directly alongside compatible circuit protection without requiring a separate DIN-rail-mounted current transformer. Combined with ABB CMS and InSite monitoring architecture, the CMS-200S8 provides detailed visibility of higher-current electrical loads in industrial, commercial and infrastructure distribution systems.
