I have a question regarding circuit breaker voltage ratings. I am looking at a breaker (the allen bradley 1489) which can be purchased in the 1/2 to 25A range for a 480Y/277VAC distribution system, or 1/2 to 40A range for a 240VAC system.
My question is, can these breakers be used in other systems?
What if I tried to use the afformentioned breaker in a 240Y/120V system? Would it trip in a different current range? Why or why not?
Thanks,
Jeff
