Product FAQs
5 answersCan I install the THQL1130ST1 in a GE A-Series panelboard?
No. The THQL1130ST1 is a plug-in breaker designed for GE Q-Line, PowerMark Gold, and ABB ReliaHome load centers. GE A-Series panelboards require bolt-on breakers like the THQB1130ST1.
What does the "ST1" suffix indicate on this THQL breaker?
The ST1 suffix indicates that this breaker includes a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely, which is commonly used for emergency stop systems or remote load shedding.
Is the THQL1130ST1 suitable for use with heating and air conditioning equipment?
Yes, this breaker is HACR rated, making it suitable for use with HVAC applications that require a 30A, 1-pole circuit.
Why might my THQL1130ST1 breaker arrive with ABB branding instead of GE?
ABB acquired GE Industrial Solutions in 2018. As a result, Q-Line breakers like the THQL1130ST1 may feature either ABB or GE branding, but they are identical in form, fit, and function.
Does the THQL1130ST1 provide GFCI or AFCI protection?
No, this is a standard thermal-magnetic breaker equipped with a shunt trip. It provides standard overcurrent and short-circuit protection, but does not include ground fault or arc fault circuitry.
