FA26040AB **Old Style** - 40 Amp Circuit Breaker Description
FA26040AB **Old Style** - 40 Amp Circuit Breaker
The FA26040AB Old Style is a 40 Amp, 2-pole molded case circuit breaker built for compatible I-Line plug-in panelboards using an A-B phase configuration. If you're maintaining an existing electrical distribution system, having the correct breaker matters. This FA-frame breaker is intended as a form, fit, and functional replacement for compatible installations, helping preserve the original panel configuration without requiring modifications.
Its thermal magnetic trip unit responds to both sustained overloads and short circuits, providing the protection expected in commercial and industrial power distribution systems.
