What is In (current rating) shown on the MCCB? Is this full load which can withstand by the circui..

Answer / chandra_edu

The current shown in mccb is like below
240/415v
9kA
20A
here 9ka means rated short circuit current when appears
during fault which mccb can withstand
and
20a is actual load current it can withsatnd
