Are all Schneider Electric breakers manufactured to NEMA AB3 requirements?

Product Line:

Circuit Breakers

Answer:

NEMA AB3 is an application guide, not a design standard. In other words, NEMA AB3 is a standard for breakers on how they are applied or used, not on how they were manufactured.

Compared to NEMA AB1, which is the design standard for all of our UL 489 breakers.
