Description
Engineered for heavy-duty industrial applications, this 175A three-pole breaker features fixed thermal and magnetic trip units for consistent LI protection. The unit-mount design includes both line and load lugs, making it ideal for standalone enclosures or motor control centers. Compatible with legacy Series C infrastructure, it serves as a robust solution before transitioning to the newer Power Defense PDG23M0175TFFL series. Rated for 65kAIC at 240VAC, it also supports reverse feed setups.Specifications

Product FAQs
6 answersWhat enclosures or panels are compatible with the ED3175L?
The ED3175L is an F-Frame circuit breaker designed for use in Eaton Series C panelboards, switchboards, and motor control centers.
What does the L in the ED3175L catalog number indicate?
The L suffix indicates that the circuit breaker comes factory-equipped with both line and load side lug terminals, which accept 4 AWG to 4/0 AWG copper or aluminum conductors.
Is the ED3175L suitable for reverse-feed applications?
Yes, this breaker is suitable for reverse-fed applications, allowing power to be supplied to either the line or load terminals.
Can the ED3175L replace an FD3175 or HFD3175 breaker?
While they share the same physical F-Frame footprint, the ED3175L is limited to a maximum of 240VAC. FD and HFD breakers are rated for up to 600VAC. You can only substitute the ED3175L if the system voltage is 240VAC or lower and the 65kA interrupting rating meets your system requirements.
Does the ED3175L support interchangeable trip units?
No, the ED3175L comes complete with a non-interchangeable thermal-magnetic trip unit.
How is the ED3175L mounted?
It is a unit mount, feed-thru circuit breaker. This means it is typically bolted directly to a mounting pan or chassis rather than plugging into a busbar.
