ABB · Air Circuit Breakers
Formula AIR
Formula AIR uses FA1, FA2 and FA4 frames with B, C and N performance levels. The page retains every workbook base combination and official commercial-reference example without treating Formula moulded-case products as Formula AIR.
A base designation for a configurable product is not a complete ABB commercial order number. Verify the moving portion, fixed part, terminals, trip unit, accessories and certification for the actual project.
