Product FAQs
8 answersWhich panelboards and enclosures accept the FD3080 circuit breaker?
This breaker is compatible with Eaton Series C panelboards, switchboards, and motor control centers that are configured to accept F-frame breakers.
What wire sizes are supported by the standard terminals?
The factory lugs on this breaker are designed to accept 14 AWG to 1/0 AWG copper or aluminum conductors.
Can the FD3080 be utilized in direct current (DC) circuits?
Yes. This model is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for specific DC distribution applications.
Are the trip settings adjustable on this breaker?
No. It is equipped with a thermal magnetic trip unit featuring fixed thermal and fixed magnetic elements. The long-time and instantaneous trip functions cannot be adjusted in the field.
How does this breaker physically connect to the panelboard bus?
It features a bolt-on mounting design. The breaker terminals bolt securely to the busbars in compatible distribution panels and switchboards, providing a stable mechanical connection.
Can internal accessories like a shunt trip be added to this breaker?
Yes. Eaton Series C F-frame breakers support a variety of field-installable internal accessories. These include shunt trips, auxiliary switches, and alarm lockouts, which mount inside the breaker housing.
What is the difference between the Eaton FD3080 and the HFD3080?
The primary difference is the short circuit interrupting capacity. The FD3080 is a standard rated breaker capable of 35kAIC at 480VAC, while the HFD3080 is a high interrupting version rated for 65kAIC at 480VAC. Both share the exact same F-frame physical dimensions.
Does this replace older Cutler-Hammer FD breakers?
Yes. Eaton and Cutler-Hammer are the same brand for this product line. A newly manufactured Eaton FD3080 is an exact, direct replacement for legacy Cutler-Hammer breakers bearing the same catalog number.

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.
