Product FAQs
8 answersWhat enclosures and panels are compatible with the QC2020 breaker?
The QC2020 is a cable-in/cable-out breaker designed for Eaton Quicklag panelboards, industrial control panels, and standalone enclosures. It can also be mounted on a standard DIN rail if equipped with the proper Eaton DIN rail adapter.
How does the QC2020 mount inside a panel?
The QC2020 is neither a plug-on nor a bolt-on breaker. It is a panel-mounted, cable-in/cable-out feed-thru breaker that uses box lugs for both line and load side wiring connections.
What is the difference between the QC2020, QCR2020, and QCF2020?
While all three are 20-amp, two-pole Quicklag breakers, their mounting styles differ. The QC2020 is the standard cable-in/cable-out version. The QCR2020 is designed for rear mounting, and the QCF2020 is designed for front mounting.
Can the QC2020 be used in DC voltage applications?
Yes, this breaker carries DC interrupting ratings. It provides a 5 kAIC rating at 48VDC and a 3.8 kAIC rating at 62.5VDC, making it suitable for low-voltage control circuits.
Is the QC2020 HACR rated for HVAC equipment?
Yes, Eaton Quicklag QC breakers from 10A to 100A, including the 20-amp QC2020, are HACR rated. They are suitable for heating, air conditioning, and refrigeration equipment circuits.
What are the accepted wire sizes for the QC2020 terminals?
The box lugs accept 14 AWG to 10 AWG copper or aluminum wire. Both line and load side connections should be torqued according to the manufacturer specifications printed on the breaker label.
How do you install the QC2020 onto a DIN rail?
Because the QC2020 is natively a panel-mount breaker, it requires an Eaton QC DIN rail adapter kit to securely attach to a standard 35mm DIN rail inside a control panel.
Does the QC2020 offer adjustable trip settings?
No, the QC2020 features fixed thermal and fixed magnetic trip mechanisms. It provides standard Long-Time and Instantaneous (LI) overcurrent protection that cannot be adjusted in the field.
