Built for commercial applications, the Eaton FDC4030 is a 30A, four-pole MCCB from the Series C F-Frame line. It provides reliable thermal-magnetic (LI) protection. This bolt-on breaker mounts into Eaton Pow-R-Line C panelboards and switchboards. It features a current-limiting design and reverse feed capability for flexible installation. Rated at 200kAIC at 240V and 100kAIC at 480V, it safely handles high fault currents. The unit is HACR rated and meets UL 489 standards.
Which panelboards are compatible with the FDC4030 circuit breaker?
This F-frame breaker is designed for use in Eaton Pow-R-Line C panelboards and industrial switchboards. It is not compatible with standard residential load centers.
What is the difference between FDC, HFD, and FD breakers?
The FDC prefix indicates an ultra-high interrupting capacity for Series C F-frame breakers. This model provides up to 100kAIC at 480VAC, which is significantly higher than the standard FD and high-interrupting HFD versions.
What wire sizes are accepted by the load side lugs on this breaker?
The factory-installed load lugs accept wire gauges from 14 AWG up to 1/0 AWG. The terminals are rated for both copper and aluminum conductors.
Can the trip settings on the FDC4030 be adjusted in the field?
No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. The trip settings cannot be modified.
Does this 4-pole breaker require a specific mounting configuration?
Yes, it requires a bolt-on connection suitable for 4-pole F-frame breakers. Ensure your Pow-R-Line C panelboard or switchboard chassis has the appropriate physical space and busbar configuration to accept a 4-pole footprint.
