Product FAQs
8 answersWhat is the difference between Eaton QC, QCR, and QCF breakers?
The difference lies in the mounting and connection type. QC breakers like the QC1030 are cable-in/cable-out (feed-thru), QCR breakers are rear-connected, and QCF breakers are front-connected.
Can the Eaton QC1030 be mounted on a standard DIN rail?
Yes, the QC1030 can be mounted on a standard 35mm DIN rail, but it requires a separate DIN rail adapter bracket, catalog number QCDINADAPT.
What type of enclosures or panels accept the QC1030 breaker?
The QC1030 is a feed-thru breaker designed for specialized control panels and industrial enclosures. It does not plug or bolt onto standard residential load center busbars.
Is the QC1030 rated for DC voltage applications?
Yes, in addition to its 10kAIC rating at 120/240V AC, the QC1030 is rated to interrupt 3.8kA at 62.5V DC.
What does the LI trip function indicate on the QC1030?
The LI designation means the breaker includes Long-Time and Instantaneous trip functions. The long-time thermal element protects against overloads, while the instantaneous magnetic element protects against short circuits.
Are Cutler-Hammer QC1030 and Eaton QC1030 the same breaker?
Yes, Eaton acquired Cutler-Hammer. The QC1030 is the exact same Quicklag miniature circuit breaker regardless of which brand name is printed on the label.
Does the QC1030 accept both aluminum and copper wiring?
Yes, the box lug terminals on the QC1030 are rated for both aluminum and copper conductors ranging from 14 AWG to 10 AWG.
Can the trip settings on the QC1030 be adjusted?
No, the QC1030 features a fixed thermal-magnetic trip unit. The long-time and instantaneous trip points cannot be modified in the field.
