Product FAQs
6 answersWhich panelboards are compatible with the TQD32175ST1 circuit breaker?
This bolt-on breaker is engineered for integration into commercial GE A-Series and Spectra Series panelboards. It is not compatible with standard residential load centers.
What does the ST1 suffix indicate on the TQD32175ST1 catalog number?
The ST1 suffix designates that this breaker includes a factory-installed shunt trip mechanism. This allows the breaker to be tripped remotely via an external control signal.
Are the thermal and magnetic trip points adjustable on this breaker?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) trip functions are factory set and cannot be modified in the field.
Why is this breaker branded as both ABB and General Electric?
ABB acquired GE Industrial Solutions. As a result, Q-Line breakers like the TQD32175ST1 may carry either the GE or ABB logo depending on the manufacturing date, but they are physically and electrically identical.
Is there a modern replacement for the TQD32175ST1 when upgrading legacy infrastructure?
Yes, if you are upgrading older panels, this TQD frame breaker can be replaced by the newer ABB Tmax XT3 series using a specific ABB retrofit kit.
Does the TQD32175ST1 provide ground fault or arc fault protection?
No, this is a standard thermal-magnetic breaker providing overload (long-time) and short-circuit (instantaneous) protection. It does not include GFCI or AFCI capabilities.
