Built for commercial use, the Eaton FD3050V is a 3-pole, 50A Series C molded case circuit breaker. It provides reliable thermal-magnetic trip functions for branch circuit protection. This F-Frame breaker installs into Eaton panelboards and motor control centers. It replaces legacy setups and can be substituted with PDG23G0050VFFJ models during upgrades. Rated 35 kAIC at 480VAC, the unit features a 50°C ambient calibration, making it ideal for high-temperature operating environments.
Which panelboards are compatible with the FD3050V circuit breaker?
This F-Frame breaker is designed for bolt-on installation in Eaton and Cutler-Hammer Series C panelboards, as well as compatible motor control centers and switchboards.
What does the V suffix mean in the FD3050V part number?
The V designates a 50°C ambient temperature calibration. This makes the breaker suitable for high-temperature operating environments, whereas standard Series C breakers are calibrated for 40°C.
Can I adjust the trip settings on the FD3050V?
No, this breaker is equipped with a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) protection parameters are factory-set and cannot be adjusted in the field.
What type of conductors can be used with the FD3050V terminals?
The factory-installed lugs are rated for both copper and aluminum (Cu/Al) conductors, accepting wire sizes from 14 AWG up to 1/0 AWG. Ensure proper torque specifications are followed during installation.
Will an Eaton FD3050V replace an older Cutler-Hammer FD3050V?
Yes, Eaton acquired Cutler-Hammer and continues to manufacture the Series C F-Frame breakers under the Eaton name. The physical dimensions, mounting, and FD3050V catalog number remain identical.
Does the FD3050V mount to a DIN rail?
No, the FD3050V is a panel-mount, bolt-on circuit breaker designed specifically for Series C chassis and compatible switchboards. It is not designed for DIN rail installation.
Is there a modern replacement for the Series C FD3050V?
Yes, for new installations or panel upgrades, Eaton's Power Defense series offers a direct equivalent. The PDG23G0050VFFJ is the modern replacement, featuring the same 50A rating, 35kAIC at 480VAC, and 50°C calibration.
Can the FD3050V be used in direct current applications?
Yes, this thermal-magnetic breaker is suitable for direct current applications. In addition to its AC ratings, it is rated for up to 250VDC with an interrupting capacity of 10kAIC.

175amp molded case circuit breaker
The breaker we purchased was as advertised. The breaker fit perfectly. We purchased reconditioned breaker and it seems to be working properly, accordingly to the golf course maintenance team that supervises the irrigation system.
Next day shipping came quickly even though the 4th of July was coming.
I wish it came with new installations hardware but that isn’t a deal breaker.
