The CMS current sensors are part of the ABB energy monitoring InSite with the control units SCU100 and SCU200. The sensors measure TRMS, AC and DC currents (instantaneous, min/max and hold values) and transmit these values to the InSite control unit via a 4-pin ribbon cable.
The sensors can be used with the protection and switching devices of the ABB System pro M compact® and enable installation directly on the protection device. The open core sensors are ideal for retrofitting in existing systems and enable installation without switching off the system.
