FA24040AB **Old Style** - 40 Amp Circuit Breaker
If you're maintaining an existing electrical distribution system, finding the right replacement breaker matters. The FA24040AB Old Style is a 40 Amp, 2-pole molded case circuit breaker built for use in compatible FA-frame I-Line plug-in panelboards and switchboards with an A-B phase configuration. Rather than changing your existing setup, this breaker is intended to match the original form, fit, and function of compatible installations.
