FA22015AB SQUARE D 2P 15A 240V AB PH I LINE is a high-quality circuit breaker designed for reliable performance in residential and commercial applications. This 15-amp, 2-pole breaker is ideal for safeguarding your electrical systems against overloads and short circuits. Compatible with various setups, it ensures efficient operation and enhanced safety.
"AB" refers to the bolt-on mounting style of this FA-frame breaker. Rather than a plug-in clip, it bolts directly to the panelboard bus, providing a more secure mechanical and electrical connection — a common requirement in commercial and industrial Square D panelboards and switchboards.
Square D's FA-frame line has seen changes over the years, and some variants may be obsolete or limited in availability through standard channels. Northern Breaker Group specializes in hard-to-find and obsolete breakers — contact us for current stock, lead time, or a compatible substitute if this exact catalog number is no longer actively manufactured.
No. The FA22015AB is a bolt-on MCCB intended for commercial/industrial Square D panelboards and switchboards that accept FA-frame devices. It is not interchangeable with Square D QO or Homeline plug-in breakers, which are designed exclusively for their respective residential loadcentres.
