What does the suffix AABA indicate on an EDB, EGB, or EJB breaker?

Issue:
I need to know how to get an auxiliary contact on my EDB breaker.

Product line:
Circuit Breakers

Resolution:
The AABA suffix includes a 1A1B auxiliary switch and a normally open alarm switch. We do not offer an auxiliary contact for these breakers without an alarm switch.
