Product FAQs
6 answersWhat applications are suitable for the QCF1030T breaker?
This Quicklag miniature breaker is designed for industrial applications, specifically for OEM control panels, enclosures, and Eaton Quicklag panelboards requiring a front-mounted, feed-thru configuration.
How does the "T" suffix affect the installation of the QCF1030T?
The "T" designation indicates that the breaker is equipped with stud or tapped pad terminals rather than standard bare-wire box lugs. It includes #10-32 terminal screws, requiring the use of properly sized ring terminals or spade lugs for line and load connections.
How is the QCF1030T secured within a control panel?
It is a front-mounted breaker that fastens directly to the panel or enclosure backpan. It uses a feed-thru, cable-in and cable-out wiring method instead of connecting directly to a panelboard busbar.
Can the trip settings on the QCF1030T be adjusted in the field?
No, this breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous (LI) protection settings are factory-calibrated and non-interchangeable.
Is the QCF1030T interchangeable with standard plug-on or bolt-on Quicklag breakers?
No. The QCF frame is specifically designed for front-panel mounting with feed-thru wiring. It cannot be used as a direct replacement for plug-on or bolt-on breakers that connect directly to a busbar.
What wire gauge is supported by the QCF1030T terminals?
The terminals on this 30-amp breaker are rated for 10 AWG wire. When crimping ring or spade lugs for the connection, ensure they are sized for 10 AWG wire and compatible with the provided terminal screws.
