Product FAQs
8 answers
Can I mount the QC2080 on a standard DIN rail?
Yes, but it requires a separate adapter. You will need one Eaton QCDINADAPT accessory per pole to securely mount this breaker to a standard 35mm DIN rail.
What is the difference between Eaton QC and QCD breakers?
The QCD series comes factory-built for DIN rail mounting. The QC series, including the QC2080, is a standard cable-in/cable-out breaker that requires the add-on QCDINADAPT accessory to be mounted on a DIN rail.
How is the QC2080 wired and what wire sizes does it accept?
This breaker features a feed-thru, cable-in/cable-out connection type. Its box lugs accept either copper or aluminum wiring ranging from 4 AWG to 1/0 AWG.
Is the QC2080 suitable for DC voltage applications?
Yes, in addition to its 120/240VAC rating, this breaker is rated for DC applications. It provides a 5 kAIC interrupting rating at both 62.5VDC and 80VDC.
What type of trip unit does this breaker use?
It utilizes a thermal-magnetic trip unit with fixed long-time and instantaneous (LI) trip functions to protect against overloads and short circuits.
What enclosures and panels are compatible with this breaker?
The QC2080 is designed for Eaton Quicklag panelboards, as well as various industrial control panels and enclosures that support feed-thru miniature circuit breakers.
Is an Eaton QC2080 the same as a Cutler-Hammer QC2080?
Yes. Eaton acquired Cutler-Hammer, so the Eaton QC2080 is the exact direct replacement for a legacy Cutler-Hammer breaker with the same catalog number.
Is this breaker HACR rated for HVAC equipment?
Yes, Eaton Quicklag QC breakers in this amperage range are HACR rated, making the QC2080 suitable for protecting heating, air conditioning, and refrigeration circuits.

My experience was great. I had the item quickly; and it was more reasonably priced than other places I checked. Not having to pay freight was an absolute bonus.
