Manual test example for release PR112/P (vers. "without key").
NOTE: the data indicating the type of CB and protection, the rated current of the
CTs and the Neutral setting are automatically identified by the PR010/T test unit.
In this example, protection function "I" is tested with curve t=k, threshold I3=1.5*In, supplying a
fault current equivalent to 2 times the rated current (In).
