General
ABB‘s FORMULA molded case circuit breaker line offers simplic-
ity and quality in some of the smallest dimensions available. The
FORMULA A1 breaker frame size ranges in amperes from 15
through 100 with protection trip units that have fixed thermal
and magnetic threshold values. The frame is available in a fixed
version with front terminals.
