Product FAQs
7 answersWhat is the difference between the Eaton ED3150 and the ED3150L?
The L suffix in the ED3150L catalog number indicates that the breaker comes factory-equipped with both line and load side lug terminals. The standard ED3150 may require lugs to be purchased and installed separately.
What enclosures and equipment are compatible with the ED3150L?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It serves as a direct form, fit, and function replacement for older Cutler-Hammer ED-frame applications.
Are the physical dimensions of the ED3150L the same as FD or HFD breakers?
Yes, the ED, FD, and HFD breakers are all part of the Eaton Series C F-frame family. A 3-pole ED3150L shares the exact same physical dimensions as 3-pole FD and HFD breakers, though their maximum voltage and interrupting ratings differ.
Can the ED3150L be reverse fed?
Yes, the ED3150L features a non-interchangeable thermal-magnetic trip unit that is suitable for reverse feed applications, allowing you to bring line power into either the top or bottom terminals.
What does unit mount mean for the ED3150L?
As a unit mount breaker, the ED3150L is designed to be bolted directly to the panel or mounting surface rather than plugging onto a busbar. It uses cable-in and cable-out connections via the included lugs.
What wire sizes do the standard lugs on the ED3150L accept?
The factory-installed lugs accept 4 AWG to 4/0 AWG copper or aluminum (Cu/Al) conductors.
Is the ED3150L rated for DC applications?
Yes, in addition to its 240VAC rating, this breaker is rated for 125VDC systems with an interrupting capacity of 10kA.
