Belonging to Eaton's Series C family, this 3-pole, 40A MCCB provides reliable long-time and instantaneous (LI) trip functions. It is built for demanding commercial and industrial environments. The unit mount design integrates into Series C panelboards, switchboards, and motor control centers. It replaces older F-frame models like the FD3040. Rated at 14kAIC at 480VAC, it includes line and load lugs. The breaker is HACR rated for HVAC equipment and supports reverse feed configurations.
What does the L suffix mean in the FDB3040L catalog number?
The L suffix indicates that the circuit breaker is supplied with factory-installed line and load terminal lugs.
Can the Eaton FDB3040L be used in reverse feed applications?
Yes. Eaton Series C F-Frame circuit breakers, including the FDB3040L, are suitable for reverse feed applications.
Which panelboards are compatible with the FDB3040L breaker?
This breaker is designed for Eaton Series C panelboards, switchboards, and motor control centers. It is commonly installed in Pow-R-Line 3A (PRL3A) and Pow-R-Line 4 (PRL4) panelboards using the appropriate F-Frame connector kits.
Is the FDB3040L rated for HVAC and lighting loads?
Yes. All Eaton F-Frame circuit breakers are HACR rated for heating, air conditioning, and refrigeration equipment. Because it is a 40A thermal-magnetic breaker, it is also rated for High Intensity Discharge (HID) lighting applications.
Can this breaker replace older Westinghouse FDB3040L models?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse circuit breaker lines. The current Eaton FDB3040L is a direct replacement for legacy Westinghouse and Cutler-Hammer breakers sharing the same catalog number.
How is the FDB3040L mounted in a panelboard?
It is a unit-mount, feed-thru circuit breaker. When installing it in panelboards like the PRL3A, it requires a specific F-Frame connector kit, such as the KPRL3AFD3 for 3-pole configurations, to properly connect to the bus.
