Product FAQs
7 answers
What does the T suffix mean on the QCF2015T catalog number?
The T suffix indicates that the breaker is equipped with stud or tapped pad terminals on the line and load sides. These are designed to accept ring or spade lugs instead of standard box lugs.
How is the QCF2015T breaker mounted in a panel?
The QCF2015T is a front-mounted, cable-in/cable-out (feed-thru) breaker. It mounts directly to the panel or enclosure using threaded steel inserts and #6-32 screws, rather than plugging onto or bolting to a busbar.
Can this breaker be installed in a standard residential load center?
No. The QCF2015T is an industrial feed-thru breaker designed for OEM control panels, enclosures, and specialized Eaton Quicklag panelboards. It will not fit in standard plug-on or bolt-on residential load centers.
What is the physical width of the QCF2015T breaker?
Quicklag QCF breakers measure 0.5 inches wide per pole. As a 2-pole breaker, the QCF2015T has a total width of 1 inch, making it a compact choice for space-constrained control panels.
Are Eaton and Cutler-Hammer QCF2015T breakers interchangeable?
Yes. Eaton acquired Cutler-Hammer, and the QCF2015T is the exact same Quicklag breaker regardless of whether it is branded as Eaton or Cutler-Hammer.
Does the QCF2015T provide GFCI or AFCI protection?
No. This breaker features standard thermal-magnetic trip technology for overload and short-circuit protection. It does not contain ground fault (GFCI) or arc fault (AFCI) circuitry.
What is the difference between the QCF and QCR breaker series?
Both are Quicklag cable-in/cable-out breakers, but they use different mounting methods. The QCF series is designed for front-mounting using threaded inserts, while the QCR series is designed for rear mounting on a standard 35mm DIN rail.
