FA24040AC - 40 Amp Circuit Breaker

FA24040AC - 40 Amp Circuit Breaker

When maintaining an existing electrical distribution system, using the correct replacement circuit breaker helps preserve the original design and operation of your equipment. The FA24040AC is a 40 Amp, 2-pole molded case circuit breaker designed for compatible FA-frame I-Line plug-in panelboards and switchboards with an A-C phase configuration. Engineered as a form, fit, and functional replacement, it is intended for installations that require this specific breaker style without modifying the existing electrical system. Its thermal-magnetic trip unit provides protection against both overloads and short circuits, while its interrupting ratings of 25kA at 240VAC and 18kA at 480VAC make it suitable for a wide range of commercial and industrial applications where those ratings are required.
