F3040 - 40Amp Circuit Breaker

F3040 - 40Amp Circuit Breaker

The F3040 is a 40 Amp, 3-pole Type F molded case circuit breaker designed for use in 480VAC electrical distribution systems requiring a 14kA interrupting capacity. Whether you're replacing an existing breaker during maintenance or restoring equipment to its original configuration, the F3040 is intended as a form, fit, and functional replacement for compatible applications. Built on an F-Frame with a thermal-magnetic, non-interchangeable trip unit, it provides the ratings and physical configuration needed for many established commercial and industrial electrical systems. Rated for operation in 40°C ambient conditions, this breaker also includes load terminals, making installation straightforward where those connections are required.
