Description
Providing reliable overcurrent protection, this 175A Series C circuit breaker is engineered for heavy-duty commercial environments. The thermal-magnetic trip unit ensures precise response to overloads. Featuring a unit-mount configuration, the device installs into various enclosures using standard cable connections rather than panelboard busbars. It acts as a substitute for standard HFD3175 units when standalone mounting is required. Built with a 65kAIC rating at 480V, it supports reverse feed.Specifications

Product FAQs
7 answersWhat does the L suffix indicate in the HFD3175L catalog number?
In Eaton Series C F-frame circuit breakers, the L suffix indicates that the breaker is supplied with both line and load terminals. Without this suffix, F-frame breakers typically come with load side terminals only.
Can I adjust the trip curve settings on the HFD3175L?
No. The HFD3175L features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous protection but does not have adjustable dials for customizing the trip curve.
Can I install the HFD3175L in a standard residential load center?
No. The HFD3175L is a unit mount, feed-thru breaker designed for Eaton Series C panelboards, switchboards, and motor control centers. It will not fit in standard plug-on residential load centers.
Is the HFD3175L suitable for reverse feed applications?
Yes, Eaton Series C F-frame molded case circuit breakers are suitable for reversed line and load connections.
What is the difference between the FD and HFD circuit breaker frames?
Both are Eaton Series C F-frame breakers with identical physical dimensions, but the HFD designates a high interrupting capacity version. For example, at 480VAC, an FD breaker is typically rated for 35kAIC, while the HFD is rated for 65kAIC.
Do I need to purchase separate lugs for the HFD3175L?
No. Because this model includes the L suffix, it comes factory equipped with both line and load lugs. These terminals accept 4 AWG to 4/0 AWG copper or aluminum conductors.
Is the HFD3175L HACR rated?
Yes, Eaton Series C F-frame circuit breakers are HACR rated, meaning they are suitable for use with heating, air conditioning, and refrigeration equipment.
