Product FAQs
6 answersWhat type of panels or enclosures are compatible with the TQC1120?
The TQC1120 is a unit-mount, feed-thru breaker designed for control panels, individual enclosures, and OEM equipment. Unlike standard residential breakers, it does not plug into or bolt onto a busbar.
Can I use the TQC1120 in a standard GE residential load center?
No. Standard GE residential load centers require plug-in (THQL) or half-inch (THQP) breakers. The TQC1120 is a unit-mount breaker with line and load lugs, intended for specialized distribution setups and control panels.
How is the TQC1120 wired during installation?
This breaker features a lug-to-lug configuration. Both the line and load sides use box lugs for direct wire connections, making it ideal for standalone mounting rather than traditional busbar installations.
Is there a direct replacement or upgraded version for the TQC1120?
Yes, for facilities updating their equipment, the TQC1120 frame is commonly superseded by the THQC1120WL. Both share the same unit-mount footprint and lug-to-lug connection style.
Are ABB and General Electric TQC breakers the same?
Yes. ABB acquired GE Industrial Solutions, so TQC series breakers may be branded as either ABB or General Electric. The physical dimensions, mounting style, and electrical ratings remain identical regardless of the logo on the label.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit provides both Long-Time (thermal) and Instantaneous (magnetic) protection. This ensures the breaker trips during prolonged overloads as well as sudden, severe short circuits.
