Hello,
I know my question is pretty simple but I feel I do not have enough knowledge.
As you all know we have magnetic breakers or thermal breakers or thermal magnetic breakers. You all have seen that on one line drawings there are two ratings near the breaker (i.e. 250 AF, 200 AT) and you know that AF represent frame setting and AT represent trip setting. But this only applies to Adjustable breakers. Here is my question:
Can magnetic breakers be adjustable with different AT ratings? I know that we can adjust their instantaneous settings that are related to short circuit protection.
