Product FAQs

7 answers
What does the ST1 suffix mean on the THQL32030ST1 catalog number?

The ST1 suffix indicates that the breaker includes a factory-installed 120VAC shunt trip accessory. This allows the breaker to be opened remotely via an external control signal.

What is the difference between the THQL32030ST1 and the THQB32030ST1?

The THQL32030ST1 is a plug-on breaker designed for load centers, while the THQB32030ST1 is a bolt-on breaker typically used in commercial panelboards. Both share the same 30A rating, 3-pole configuration, and 120V shunt trip accessory.

Can I install the THQL32030ST1 in a commercial GE lighting panel?

Yes, this breaker is compatible with GE AQ Lighting Panels as well as residential GE PowerMark Gold Load Centers, provided the specific panel interior accepts plug-on THQL frame breakers.

Does the shunt trip require a separate power source?

Yes, the 120VAC shunt trip mechanism requires an external 120V control voltage to actuate the trip coil. When voltage is applied to the shunt trip leads, the breaker will open.

What are common applications for the shunt trip feature on this breaker?

The shunt trip is typically used for emergency shutdown systems. It allows the breaker to be tied into fire alarm panels, emergency stop push buttons, or equipment safety interlocks that require a rapid remote power disconnection.

Can I use aluminum wiring with the THQL32030ST1?

Yes, the box lugs on this breaker are rated for both copper and aluminum conductors. The terminals accept 14 to 8 AWG copper wire or 12 to 8 AWG aluminum wire.

Does this breaker provide ground fault or arc fault protection?

No, the THQL32030ST1 is a standard thermal-magnetic breaker providing long-time and instantaneous trip functions for overload and short-circuit protection. It does not include GFCI or AFCI capabilities.

    Part arrived, would have been nice to receive a packing slip or something in the box beside the part.
