Yes. Eaton F-Frame thermal magnetic circuit breakers, including the FD3150L, do not have line and load markings and are suitable for reverse feed applications.
What does the L in the FD3150L catalog number indicate?
The L indicates that the circuit breaker comes factory equipped with both line and load side lug terminals.
What is the difference between the Eaton FD3150L, HFD3150L, and FDC3150L?
These breakers share the same physical F-Frame dimensions and 150A rating, but they have different interrupting capacities. The FD3150L is the standard tier (35kAIC at 480VAC), the HFD3150L is high interrupting (65kAIC at 480VAC), and the FDC3150L is extra-high interrupting (100kAIC at 480VAC).
What replacement lug kit is compatible with the FD3150L?
The standard replacement lug kit for a 150A F-Frame breaker is the 3TA150FB, which includes three terminals that accept 4 AWG to 4/0 AWG copper or aluminum wire.
Does the FD3150L have adjustable trip settings?
No. This breaker features a fixed thermal and fixed magnetic trip unit, meaning the long-time and instantaneous trip functions cannot be adjusted in the field.
Can I use the FD3150L in a DC circuit?
Yes. The FD3150L is rated for use in DC applications up to 250VDC, with a 10kAIC interrupting rating.
How does the FD3150L mount into a panel?
The FD3150L is a unit mount, feed-thru circuit breaker. It bolts directly to the chassis or mounting pan in compatible Eaton Series C panelboards, switchboards, and motor control centers.
What safety precautions are required before inspecting the FD3150L?
Always verify that the breaker is switched to the OFF position and that no voltage is present. Eaton warns that special attention must be paid to reverse feed applications to ensure the equipment is fully de-energized before maintenance.

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.
