Product FAQs
6 answersCan I install the THQB32035ST1 in a standard GE Powermark Gold residential load center?
No. THQB breakers feature a bolt-on connection and will not fit plug-on residential load centers like the Powermark Gold series. They are specifically designed for commercial A-Series panelboards and AQ lighting panels.
What does the ST1 suffix indicate on this breaker?
The ST1 suffix means this breaker includes a factory-installed 120VAC shunt trip. This allows for remote tripping of the breaker via an external control signal, which is commonly used for emergency shutdown systems.
Does the shunt trip require a separate power source?
Yes. The factory-installed shunt trip requires an external 120VAC control voltage to actuate the trip mechanism. It does not draw power from the breaker's primary load circuit to operate the remote trip function.
Is this breaker manufactured by GE or ABB?
ABB acquired GE Industrial Solutions in 2018. This breaker may be branded as GE, ABB, or GE by ABB, but the THQB32035ST1 catalog number and physical specifications remain identical.
What is the difference between THQB and THHQB breakers?
The primary difference is the interrupting capacity. Standard THQB breakers like the THQB32035ST1 are rated for 10kAIC, while THHQB breakers offer a higher 22kAIC rating for systems with higher available fault current.
Does this breaker provide ground fault or arc fault protection?
No. The THQB32035ST1 features a standard thermal-magnetic trip unit for overload and short-circuit protection. It does not include GFCI or AFCI functionality.
