11.8.1.3 Digital status data: profile 1
1) The last cause of tripping registered is always indicated. The circuit-breaker is reset by switching it on, or by switching the
power supply off/on. It may take up to 30 s before the trip reason is displayed.
After a trip, the last current values measured are displayed (rms values).
