Product FAQs

5 answers
How many panel spaces does the THQDL21225 require?

Although it is a 2-pole breaker, the larger THQDL frame requires four standard 1-inch spaces when installed in GE PowerMark Gold or PowerMark Plus load centers.

Can the THQDL21225 be used to replace a TQDL21225?

Yes. The THQDL21225 is a direct replacement and upgrade for the TQDL21225, offering a higher 22kAIC interrupting rating compared to the 10kAIC rating of the standard TQDL model.

Is this breaker suitable for HVAC equipment?

Yes, the THQDL21225 is fully HACR rated, making it approved for use with heating, air conditioning, and refrigeration systems.

Is the THQDL21225 intended for use as a main breaker or a branch breaker?

It is commonly installed as a main breaker in 225A GE load centers, but it can also be used as a high-capacity branch breaker depending on your specific panel configuration.

Does this breaker include ground fault or arc fault protection?

No. This is a standard thermal-magnetic breaker designed for overload and short-circuit protection. It does not feature GFCI or AFCI capabilities.
