FA26050AC **Old Style** - 50 Amp Circuit Breaker

FA26050AC **Old Style** - 50 Amp Circuit Breaker

The FA26050AC Old Style is a 50 Amp, two-pole molded case circuit breaker built for compatible I-Line electrical distribution systems. It's most often installed as a replacement for an existing FA-series breaker where matching the original design is important. Keeping the same mounting style, electrical ratings, and phase configuration helps preserve the panel's original layout without requiring modifications.

You'll typically find this breaker in commercial and industrial facilities, protecting 240 VAC and 480 VAC branch circuits. Since it's an Old Style A-C phase model, it's important to verify that it matches the breaker being replaced before installation.
