results are negative.
Initialization
•
The three phase currents running through the 3RB3 must be as
symmetrical as possible.
•
The phase currents must be
≥
80 % of the set current
I
e
.
•
The currents must flow at least for the time
t
1
before the test.
•
The phase currents must be at least the same size as the value for
the lower setting mark of the current setting.
Test implementation
During the test all the protective functions are still active. The test is
initiated by pressing the TEST button (see device test in operating
instructions).
After the TEST button has been pressed, the device must trip within the
following time periods:
