Eaton QC1050T – Frequently Asked Questions
1) Will a Type QC breaker fit in my Eaton BR or CH panel?
No. Type QC is a non-interchangeable breaker, meaning it is built for Type QC panelboard interiors only and will not drop into a BR or CH load center. Confirm the panel label calls for QC before ordering.
2) Can I use the single-pole QC 50A breaker on a 240V circuit?
Not on its own. The single-pole QC1050T protects one ungrounded conductor for a 120V circuit. For a 240V two-wire load use the two-pole QC2050, which opens both hot legs together. The voltage rating on both is 120/240V.
3) What kind of terminals does the Eaton QC breaker use for wiring?
It is a cable-in/cable-out breaker using ring or spade lug terminals, so the conductors land directly on the breaker rather than the breaker plugging onto a bus stab. Plan on crimped ring or spade lugs on your 50A conductors at termination.
4) Does a thermal-magnetic breaker protect against both overload and short circuit?
Yes. The thermal element in the QC breaker handles sustained overloads (the slow heating from too much continuous load), and the magnetic element trips instantly on a short-circuit or ground-fault level surge. It is not a GFCI or AFCI device, so if the circuit needs ground-fault or arc-fault personnel protection that has to come from a separate device.
5) How much room does the Eaton QC breaker need in the panel?
Published dimensions are 1.1 in width, 3.7 in length/depth, and 4.8 in height. The 3.7 in depth is the number to check against your enclosure and gutter space when the breaker sits behind a cover.
