Trip / Warning History The E300 Electronic Overload Relay provides a trip and warning history in
which the last five trips and last five warnings are recorded into non-volatile
storage. A mask is available to limit which trip and warning events are logged to
the history's memory.
Trip History
When the E300 Electronic Overload Relay issue a trip, the reason for the trip is
recorded into the Trip History. Listed below are the codes that are available for
the trip history records.
