Product FAQs
6 answersCan I use the ABB THQLQ151515 to replace an older GE THQLQ151515?
Yes. ABB acquired GE Industrial Solutions, and this breaker is a direct, code-compliant replacement for the legacy GE THQLQ151515. It is fully compatible with GE PowerMark Gold and PowerMark Plus load centers.
How much panel space does this quadplex breaker occupy?
The THQLQ151515 requires two standard 1-inch spaces (2 inches total) in a compatible load center. It provides four poles of protection, maximizing circuit density without requiring a subpanel.
Does this breaker require a panel with rejection clips or wing stabs?
No. The THQLQ151515 features a standard plug-on connection that does not require half-inch wing stabs, allowing it to be placed in any standard slot within a compatible ABB or GE panelboard.
How are the 15A circuits configured on this quad breaker?
The breaker houses two independent 1-pole 15A circuits on the outer poles and one 2-pole 15A circuit on the inner poles. The center 2-pole configuration features a common trip mechanism for 240V loads.
Do the center poles on the THQLQ151515 feature a common trip?
Yes, the inner 2-pole 15A circuit utilizes a common trip mechanism. If one leg of the 240V circuit experiences an overload or short circuit, both center poles will trip simultaneously to safely disconnect the load.
Is the THQLQ151515 rated for switching duty and HVAC applications?
Yes, this breaker carries both SWD (Switching Duty) and HACR (Heating, Air Conditioning, and Refrigeration) ratings, making it suitable for controlling fluorescent lighting circuits and HVAC equipment.
