Product FAQs
6 answersHow is the TQC1150 circuit breaker installed?
This is a unit-mount, feed-thru breaker. It uses a cable-in, cable-out lug configuration rather than snapping or bolting onto a panel busbar. It is typically mounted directly in control panels or individual enclosures.
Will the TQC1150 fit in a standard GE PowerMark Gold load center?
No. PowerMark Gold load centers require plug-on THQL or THQP breakers. The TQC1150 is a feed-thru, unit-mount breaker designed for standalone enclosures and control panels.
Are ABB and General Electric TQC1150 breakers interchangeable?
Yes. ABB acquired the GE Industrial Solutions division. Breakers with the TQC1150 catalog number are identical in fit and function regardless of whether they feature the ABB or GE logo.
What type of conductors can be used with the TQC1150 box lugs?
The factory-installed box lugs are rated for both copper and aluminum conductors. They accept wire sizes ranging from 8 AWG up to 3 AWG.
How does the trip unit function on the TQC1150?
It features a fixed thermal-magnetic trip unit. The thermal element provides delayed tripping for overloads, while the magnetic element offers instantaneous tripping for short circuits.
What does the LI trip function code mean on this breaker?
The LI designation stands for Long-Time and Instantaneous trip functions. This is the standard thermal-magnetic protection profile used to prevent damage from both sustained overcurrents and sudden faults.
