It depends on circuit breaker. If sensing eliment is
installed inside the CB or outside the CB. Like MCCB with
maganetic trip latch will operate. Same way MCB will also
operate as it has short ckt and O/L sensing eliment. But
large circuit breakers have relays outside.

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
