Accurate Circuit-Level Current Monitoring

The ABB CMS-102PS enables individual branch circuits to be measured within compact electrical distribution systems. Its 0.1–20 A measurement range makes it particularly suitable for lower-current circuits where detailed information about electrical loading and consumption is required. The sensor's compact solid-core design allows multiple measuring points to be incorporated into a distribution board without the space requirements of conventional current transformers.

When incorporated into a compatible ABB monitoring system, CMS sensors provide circuit-level measurement data that can support energy-efficiency analysis, load supervision and electrical-system optimisation. The CMS-102PS is particularly useful where operators need greater visibility than can be obtained from measuring only the overall incoming supply.
