Product FAQs
6 answersWhat does the T suffix indicate on the QCF1020T catalog number?
The T suffix means this breaker is equipped with ring or spade lug terminals on both the line and load sides. It includes a #10-32 terminal screw for secure connections, replacing the standard box lugs found on the base QCF1020 model.
How is the Eaton QCF1020T circuit breaker mounted in a panel?
The QCF series is designed for front-mounted, cable-in and cable-out applications. It features two threaded steel inserts that allow the breaker to be front-mounted to a backpan or enclosure door using #6-32 steel screws.
Does the QCF1020T mount on a DIN rail or is it panel mounted?
The QCF1020T is designed for front panel mounting using two threaded steel inserts. While sometimes confused with DIN rail breakers, true 35mm DIN rail mounting in this 1/2-inch form factor requires the Eaton QCR series, such as the QCR1020T.
Is the QCF1020T rated for switching lighting loads?
Yes, this 20-amp single-pole breaker carries an SWD (Switching Duty) rating. This means it is tested and approved for regularly switching fluorescent lighting loads on and off.
What is the physical width of the QCF1020T breaker?
This single-pole Quicklag QCF breaker is 1/2-inch wide. The narrow profile is designed to save space in high-density OEM control panels and industrial enclosures.
How should wire be prepared for the terminals on this breaker?
The terminals accept 14 AWG to 4 AWG copper or aluminum wire. Because this model features tapped pad terminals, the wire must be crimped with a compatible insulated ring or spade connector before being secured by the provided terminal screws.
