Introduction
ABB’s FORMULA molded case circuit breaker line offers simplicity and quality in some of
the smallest dimensions available. The A1 breaker frame size ranges in amperes from 15
through 100 and the A2 breaker frame size ranges from 125 through 250 amperes. All UL
FORMULA circuit breakers offer protection trip units that have xed thermal and magnetic
threshold values and are standard as a xed version with front terminals.
