Issue:
What does the description 1A or 1B on auxiliary switches mean?

Product Line:
Molded Case Circuit Breakers

Resolution:
1A1B = 1 normally open (1A) and 1 normally closed (1B) contact.
2A2B = 2 normally open and 2 normally closed contacts.
3A3B = 3 normally open and 3 normally closed contacts.
The "normal" status applies to the breaker when the breaker is open.
