The FA24050BC is an FA-frame commercial plug-in breaker intended for Square D FA-series panelboards and compatible commercial switchboards. It is not designed for residential QO or Homeline loadcentres. Share your panelboard model number with our team and we'll confirm compatibility.
The 'BC' designation refers to the Boot Connector terminal configuration on this breaker, associated with a Phase I Line (PH I LINE) lug arrangement. This affects how the breaker connects to the bus and field wiring, so it's important to verify that your panelboard and wiring setup match this terminal type before installation.
Square D FA-frame breakers are considered a legacy commercial product line, and availability can be limited. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so we can often source original FA24050BC units. We can also advise on any factory-approved equivalents if a direct replacement is unavailable — contact us for a quote and availability check.
