ABB THQLQ202020 – Frequently Asked Questions

1) Will an ABB Q-Line quad breaker fit a GE PowerMark load center?
Yes. The Q-Line THQLQ quad plugs into new and existing single-phase ABB and GE by ABB PowerMark load centers, with or without wing stabs. It is a plug-in breaker, not a bolt-on, so it seats on the panel's stab bus the same way a standard Q-Line breaker does.
2) What does the 2-1P+1-2P quad configuration actually give me in the panel?
In four panel spaces you get two independent single-pole circuits on the outer positions plus one two-pole (240V) circuit on the inner positions. That is three usable circuits where a pair of standard two-pole breakers would give you two. It is the common fix when a panel is full and you need to add a 240V load, like a small AC condenser, without swapping the load center.
3) What amperage combinations does the ABB Q-Line quad come in?
Three combinations are offered: THQLQ151515 (15A), THQLQ202020 (20A), and THQLQ203020, which pairs 20A outer poles with a 30A two-pole center. Pick the one that matches the branch circuit loads you are adding, since the trip range is non-interchangeable and the breaker cannot be re-rated in the field.
4) Is 10kA interrupt rating enough for my service?
The Q-Line quad is rated 10kA at 120 Vac and 10kA at 120/240 Vac, which covers typical single-phase residential and light commercial services. If your available fault current at the panel exceeds 10kA, per the utility or a short-circuit study, you need a higher AIC breaker and this one will not qualify.
5) Can I swap a quad breaker into any breaker slot in my panel?
No. A quad occupies four adjacent spaces and the two-pole center section has to land on opposing bus legs, so it needs a full four-space run in a single-phase ABB or GE by ABB PowerMark panel. Some panels also restrict how many tandem or quad devices they will accept on the label, so check the load center's circuit limitation before you count on the extra circuits.
6) Can a Square D PowerPacT B breaker be used in place of an ABB Q-Line quad breaker?
No. The ABB Q-Line Quad is a plug-in branch breaker in a quad footprint that combines 2-1P plus 1-2P poles on a 120/240V single-phase load center bus, and it is built to seat in ABB and GE by ABB PowerMark load centers with or without wing stabs. The Square D PowerPacT B is a molded case thermal magnetic breaker from the PowerPacT B series - a different frame and mounting arrangement entirely, not a plug-in replacement for a quad branch position. If you are filling stabs in a PowerMark panel, stay with the Q-Line quad.
7) Can I use this quad breaker on an air conditioning circuit?
Yes. The Q-Line quad carries an HACR SWD load rating, so it is suitable for heating, air conditioning and refrigeration branch circuits and for switching duty (lighting circuits switched at the breaker).
8) What wire size does the ABB THQLQ quad breaker accept?
Each pole lug takes (2) conductors, #14-8 copper or #12-8 aluminum. That means you can land two conductors per terminal within those ranges, which matters when you are pigtailing or feeding two loads off one pole.
9) What is the difference between the ABB Q-Line quad breaker and a Square D C60 DIN rail breaker?
Mounting and application. The ABB Q-Line Quad is a plug-in load center breaker rated 120/240V, listed under UL E11592, and intended for single-phase residential and light commercial panelboards where it adds circuits without adding panel width. The Square D C60 is a UL489 miniature circuit breaker that mounts on DIN rail, which is what you use inside a control panel or equipment enclosure rather than a residential load center. They are not interchangeable in either direction.
10) I need a single-pole 120V branch breaker, not a quad - what should I look at instead?
The ABB Q-Line Quad is a combined unit, 2-1P plus 1-2P in one quad footprint, so it is the wrong choice if you only need one circuit. For a single-pole 120V AC device, the Square D Multi9 C60 1-pole C-curve miniature circuit breaker covers that configuration. Check which panel you are feeding first - the Q-Line quad is the plug-in option for ABB and GE by ABB PowerMark load centers.
11) Is the ABB Q-Line quad breaker UL listed?
It is listed under UL file E11592, which is the standard reference cited for the Q-Line breaker platform.
