Can someone explain how a current limiting circuit breaker works? Does the breaker have some other feature besides an instantaneous pickup for clearing a fault quickly thus making it current limiting?
I understand that to be current limiting the fault current must fall the the right of the instantaneous pickup vaule. How is this ensured and how does this limit fault magnitude?
