FA24050AC - 50 Amp Circuit Breaker

FA24050AC - 50 Amp Circuit Breaker

The FA24050AC is designed for one job—providing a compatible replacement in existing FA-frame I-Line electrical systems. If you're maintaining equipment that calls for this exact configuration, having the right breaker helps keep the system operating as intended. This 50 Amp, 2-pole molded case circuit breaker uses a thermal-magnetic trip unit that responds to both sustained overloads and sudden short circuits, offering protection for branch circuits and connected equipment during normal operation.

Built for 60Hz applications, the FA24050AC features an A-C phase, I-Line plug-in design that fits compatible panelboards and switchboards without changing the original layout. It is rated for 25 kA at 240 VAC and 18 kA at 480 VAC, making it suitable for installations that require those interrupting capacities.
