Description
Built for industrial systems, the GE TQD32150ST1 is a 3-pole, 150A molded case circuit breaker delivering reliable thermal-magnetic protection with long-time and instantaneous (LI) trip functions. This unit-mount breaker installs into GE A-Series and Spectra panelboards. For modern replacements, the ABB XT3 frame serves as the substitute, requiring a retrofit kit and shunt trip accessory. A factory-installed 120VAC shunt trip enables remote shutdown. It provides a 10kAIC rating at 240VAC.Specifications

Product FAQs
6 answersWhich GE panelboards accept the TQD32150ST1 breaker?
This unit-mount breaker is compatible with GE A-Series and Spectra Series panelboards. It bolts directly to the chassis rather than using a plug-in connection.
What does the ST1 suffix specify on the TQD32150ST1?
The ST1 suffix indicates the breaker is equipped with a factory-installed 120VAC shunt trip, enabling remote shutdown capabilities.
Do I need special lugs to terminate aluminum wire on the TQD32150ST1?
No. The breaker comes with factory-installed lugs that are rated for both copper and aluminum conductors, accepting wire sizes from 1 AWG up to 300 kcmil.
Is the TQD32150ST1 suitable for 480V applications?
No. This model is strictly rated for 240VAC maximum, delivering a 10kA interrupting rating. It cannot be safely installed in 277/480V or 480V systems.
Are ABB and GE versions of the TQD32150ST1 fully interchangeable?
Yes. Following ABB's acquisition of GE Industrial Solutions, TQD series breakers may carry either brand name. They are identical in form, fit, and function.
What is the recommended ABB upgrade for a legacy TQD32150ST1?
The ABB XT3 molded case circuit breaker serves as the modern replacement. Upgrading requires a TQD to XT3 retrofit kit, as well as a separate 120VAC shunt trip accessory to replicate the original breaker's functions.
