Product FAQs
5 answersWhich panelboards accept the TXQB1120 circuit breaker?
This breaker is compatible with GE A-Series panelboards and GE AQ lighting panels. It requires a busbar designed for bolt-on Q-Line breakers.
Will the TXQB1120 fit in a standard GE residential load center?
No. This is a bolt-on breaker designed for commercial panelboards. Standard GE residential load centers require plug-on breakers, such as the THQL series.
Can the TXQB1120 replace a THQB1120 or THHQB1120?
Yes. The TXQB1120 shares the exact same physical dimensions and bolt-on mounting as the THQB1120 and THHQB1120. It serves as a direct replacement while providing a significantly higher interrupting rating of 65kAIC.
Why would I need the 65kAIC rating of the TXQB1120?
The 65kAIC rating allows the breaker to safely clear up to 65,000 amps of fault current. This high interrupting capacity is often required in commercial, industrial, or high-density environments where the available fault current exceeds the limits of standard 10kAIC or 22kAIC breakers.
Is the TXQB1120 rated for use with HVAC equipment and fluorescent lighting?
Yes. This breaker is HACR rated for use with heating, air conditioning, and refrigeration equipment. It is also SWD rated, meaning it can be used to safely switch 120V fluorescent lighting loads on and off.
