Hi all,
I am currently using ABB circuit breakers, which has an uninterruptible current rating equal to their frame size. However the long time pickup of their associated trip devices has a tolerance of 1.05 to 1.20. Does the continuous current rating of the CB preclude me from using the maximum long time pickup setting? Any advice is appreciated.
