Built for industrial power systems, the Eaton FD3030 is a 3-pole, 30A molded case circuit breaker from the Series C F-Frame family. It utilizes a panel mount configuration with load side lugs, integrating seamlessly into compatible Eaton switchboards and motor control centers. Delivering 35 kAIC at 480VAC, it relies on proven thermal-magnetic technology for long-time and instantaneous (LI) protection. The breaker is HACR rated, current limiting, and supports reverse feed applications.
What panels and enclosures are compatible with the FD3030 breaker?
This breaker is designed for use in Eaton Series C Panelboards, Switchboards, and Motor Control Centers that accept F-Frame breakers.
Can the FD3030 be reverse fed?
Yes. Eaton Series C F-Frame circuit breakers, including the FD3030, are suitable for reverse feed applications.
Does the FD3030 come with connection lugs?
Yes, it includes standard load-side lugs that accept 14 AWG to 1/0 AWG copper or aluminum wire. The line side is designed for a bolt-on connection directly to the panel bus.
Can I use the FD3030 to replace an ED3030?
Yes. The FD3030 has a higher voltage capacity (up to 600VAC) and higher interrupting ratings than the ED frame, which is limited to 240VAC. Both breakers share the same physical F-Frame footprint.
What is the difference between the FD3030, HFD3030, and FDC3030?
They share the same 30-amp continuous current rating and Series C F-Frame dimensions but differ in interrupting capacity at 480VAC. The FD3030 is rated at 35kAIC, the HFD3030 at 65kAIC, and the FDC3030 at 100kAIC.
Is the FD3030 suitable for DC applications?
Yes. This breaker is rated for up to 250VDC with a 10kAIC interrupting capacity, making it suitable for direct current industrial control and switching tasks.
Is the FD3030 HACR rated?
Yes. All Eaton Series C F-Frame molded case circuit breakers are HACR rated for safe use with heating, air conditioning, and refrigeration equipment.
Is the FD3030 rated for HID lighting?
Yes. All Eaton F-Frame circuit breakers ranging from 10 amps to 50 amps, including the 30A FD3030, are rated for High Intensity Discharge (HID) lighting use.
Can the thermal-magnetic trip unit on the FD3030 be adjusted?
No. The FD3030 features fixed long-time thermal and fixed instantaneous magnetic trip functions, meaning the trip thresholds cannot be modified in the field.

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.
