115
Maintenance
CB status: contact wear and last maintenance 116
Operation counters
Number of mechanical and electrical operations 116
Instantaneous currents
The instantaneous currents, available in the
Measurements
pages, are real time measurements of the
phase and earth fault currents expressed in root mean square value; the monitor time and performance
depend on the rated current defined by the Rating plug (In):
