BRE (Breaker Report)
Access Levels 1, B, 2
Use the BREAKER command to display a report of breaker operation
information. The breaker report provides trip counter and trip current
information for up to four breakers. The summary of the operations provides
valuable breaker diagnostic information at a glance. An example breaker
report follows. Refer to Section 5: Metering and Monitoring for further
information. If the Analog Input Label settings (IAW1, etc.) have been
renamed, these will appear in the report as set.
