Answer Posted / pillay
making capacity of a circuit breaker means when you switch
on the breaker the breaker can operate safely or withstand
upto the stated amount.
The same applys to breaking capacity of a breaker which
means when it switches off it can withstand up to the stated
amount at the time of offing. The unit used is usually KVA
or MVA.
Some breakers can have a high breaking capacity but a low
making capacity. This means when switching on it should not
be loaded but can be switched OFF with a high load.
