load which can withstand by the circuit breaker
Answers were Sorted based on User's Feedback
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

Answer / devesh mishra
ln=200A means the full/maximum load current(200A) beyond which the MCCB trips due to overload.
9KA stands for the breaking capacity.
