Product FAQs
8 answersWhat does the ST1 suffix indicate on the THQL32080ST1?
The ST1 suffix means this breaker includes a factory-installed 120VAC shunt trip. This allows the breaker to be opened remotely by an external control signal, such as a fire alarm interface or emergency stop button.
Which panelboards are compatible with the THQL32080ST1?
This plug-in Q-Line breaker is designed for GE A-Series panelboards, specifically Types AL and AQ. It will not fit panels requiring bolt-on branch breakers.
Can I install this plug-in breaker in a panel that requires bolt-on connections?
No. The THQL series features a plug-in connection. If your GE panelboard requires bolt-on branch breakers, you must use the THQB series equivalent, such as the THQB32080ST1.
Are ABB and GE THQL circuit breakers interchangeable?
Yes. ABB acquired GE Industrial Solutions, and current production breakers may carry ABB, GE, or combined branding. They retain the same catalog numbers and are fully interchangeable for form, fit, and function.
What are the accepted wire gauges for the THQL32080ST1 box lugs?
The lugs accommodate 6 AWG to 1/0 AWG copper wire, or 4 AWG to 1/0 AWG aluminum wire. Always verify local codes for proper ampacity sizing and apply the manufacturer torque specifications printed on the breaker.
How does the shunt trip mechanism operate on this breaker?
The internal shunt trip coil is actuated by an external 120VAC control circuit. When voltage is applied to the coil leads, it mechanically forces the breaker to trip and open the circuit.
Is this breaker suitable for HVAC or generator emergency shutdown circuits?
Yes. The integrated 120V shunt trip makes this breaker ideal for commercial and light industrial applications that require a remote disconnect, including HVAC shutdowns and generator control panels.
How does the remote trip interact with the standard breaker protections?
The 120VAC shunt trip operates independently of the primary protection. The breaker still utilizes its thermal-magnetic Long-Time and Instantaneous (LI) functions to automatically trip during overloads or short circuits, even if no remote signal is sent.
