Product FAQs
7 answersWhat is the difference between the Eaton FDB3070 and the FD3070?
Both are 70A, 3-pole Series C F-frame circuit breakers with identical physical dimensions. The difference is their interrupting capacity. The FDB3070 is rated for 14kA at 480VAC, while the FD3070 has a higher interrupting rating of 35kA at 480VAC.
Can the FDB3070 circuit breaker be reverse fed?
Yes. Eaton Series C F-frame thermal-magnetic circuit breakers, including the FDB3070, do not have line and load markings and are suitable for reverse feed applications.
Which Eaton panelboards are compatible with the FDB3070?
This F-frame breaker is designed for use in Eaton Pow-R-Line C panelboards, specifically the PRL3a and PRL4 models, when equipped with the correct connector kits. It is also compatible with various Eaton switchboards and motor control centers.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time overload protection and Instantaneous short-circuit protection. On the FDB3070, both the thermal and magnetic trip points are fixed and cannot be adjusted.
Is the FDB3070 HACR rated for use with heating and cooling equipment?
Yes. All Eaton Series C F-frame circuit breakers carry an HACR rating, making them suitable for use with heating, air conditioning, and refrigeration equipment.
Can I use this Eaton breaker to replace an older Cutler-Hammer or Westinghouse FDB3070?
Yes. Eaton acquired the distribution equipment businesses of both Cutler-Hammer and Westinghouse. An Eaton FDB3070 is the exact direct replacement for legacy Cutler-Hammer and Westinghouse breakers sharing the same catalog number.
Does the panel-mount FDB3070 include both line and load lugs?
No. Standard panel-mount F-frame breakers typically include load-side lugs only, as the line side connects directly to the panelboard bus or connector kit. The included load lugs accept 14 to 1/0 AWG copper or aluminum wire.
