FA26040AC - 40 Amp Circuit Breaker

FA26040AC - 40 Amp Circuit Breaker

The FA26040AC is a 40 Amp, 2-pole molded case circuit breaker built for compatible I-Line plug-in panelboards using an A-C phase configuration. When you're replacing an existing breaker, matching the original specifications is the best way to keep the panel operating as intended. This FA-frame breaker is designed as a form, fit, and functional replacement, making it a practical choice for maintenance work in commercial and industrial electrical systems without changing the original panel layout.
