Indications on operation

In the case of testing with the SACE PR010/T unit for G protection function, the maximum trip
time tolerance value is 35%. The minimum threshold is 0.6 x In for the manual test.

Example of an automatic test application

on the PR111/LSI unit fitted on CB E1B12, with CT

= 800 A, Neutral = 50%.

[Make sure the default setting is programmed for automatic testing as shown under the heading
"Default setting for automatic PR111/P testing"].
