Square D QO 2-Pole Plug-In Ground Fault Circuit Breaker, 120/240VAC 10kA

The Square D QO 2-Pole Plug-In Ground Fault Circuit Breaker delivers combined overcurrent and ground fault protection for residential and light commercial panelboards. This Class A, 6mA ground fault breaker is rated 120/240VAC with a 10kA interrupting capacity, and the QO breaker platform is available across a range of amperage ratings from 20A to 60A to match branch-circuit loads in compatible QO panelboards. Every breaker in the family shares the same trip-free toggle mechanism, plug-in mounting with pigtail lead connection, and UL Listed, CSA Certified, TAA compliant construction, so you can standardize on QO ground fault protection across an entire panel while selecting the amperage that fits each circuit.

Square D QO260GFI – Frequently Asked Questions

1) Will a Square D QO 2-pole GFCI breaker fit any QO load center?
It's a plug-in breaker built for Square D QO panelboards and load centers, and it takes two spaces in the panel. The pigtail lead lands on the panel neutral bar, so you need a panel with an accessible neutral and two adjacent open spaces on opposite phases for 120/240VAC. It won't plug into Homeline or another manufacturer's bus.
2) Is this a Class A 6mA GFCI or a 30mA equipment ground fault breaker?
Class A, 6mA sensing, which is personnel protection, not equipment protection. If your spec calls for a 30mA GFPE device for heat trace or similar equipment protection, this is not that breaker.
3) Is a 10kA interrupting rating enough for my panel?
The QO 2-pole GFCI is rated 10kA interrupting at 120/240VAC, which is the standard AIC for residential and light commercial load centers. If your fault current study or drawing calls for 22kA or higher at the panel, this breaker does not meet it and you need a higher-AIC device.
4) Can I use this QO GFCI breaker for a 240V circuit with no neutral, like a hot tub heater?
Yes. The breaker's pigtail is the sensing neutral and must land on the panel neutral bar regardless. If the load itself needs a neutral (120/240V equipment), that neutral goes to the breaker's load neutral terminal, not the panel bar. Straight 240V loads use the two hot terminals only, with the pigtail still connected.
5) Will this replace an existing standard QO 2-pole breaker in my panel?
It plugs into the same QO bus and occupies the same two spaces, so mechanically it's a direct swap for a standard QO 2-pole. The difference is wiring: you'll need to move the circuit neutral (if any) from the panel neutral bar to the breaker's load neutral terminal and connect the breaker pigtail to the bar.
6) Can an ABB A2N or E150 molded case breaker be used in place of a Square D QO 2-pole GFCI breaker?
No. The Square D QO 2-pole ground fault breaker is a plug-in branch breaker built for QO load centers, rated 120/240VAC with Class A 6mA ground fault sensing and a pigtail neutral lead. The ABB A2A150TT is an A2 Series 3-pole molded case breaker and the ABB TEB is an E150 Series 3-pole thermal magnetic breaker - both are three-pole molded case devices, not two-pole plug-in units for a QO panel interior, and neither provides the 6mA personnel ground fault function. Use them only where a molded case three-pole breaker is what the drawing calls for.
7) What wire sizes will the QO GFCI breaker lugs accept?
AWG 14 through AWG 8 copper, or AWG 12 through AWG 8 aluminum. Tightening torque runs 4 to 4.6 N.m. That range covers a 20A circuit up to a 60A feed at the top end of the lug capacity.
8) Does the QO GFCI breaker meet TAA requirements for a federal job?
Yes, it's TAA compliant, so it clears Trade Agreements Act sourcing for federal and government work. It's also UL Listed and CSA certified.
9) How does a QO GFCI breaker differ from molded case breakers like the ABB A2N or XT4?
Different class of device. The QO 2-pole GFCI is a plug-in branch breaker for QO residential and light commercial load centers with Class A ground fault sensing built in. The ABB A2N Series and XT4 Series are 3-pole molded case breakers for distribution equipment, and the ABB ST200M is a UL1077 supplementary protector, not a branch circuit breaker. None of those are interchangeable with a QO panel bus.
10) Is an ABB ST200M miniature circuit breaker an alternative to the QO 2-pole GFCI breaker?
They serve different roles. The ABB ST200M is a miniature circuit breaker built to UL1077, which is a supplementary protection standard, and it is a DIN-rail style device rather than a plug-in load center breaker. The Square D QO 2-pole ground fault breaker is UL Listed branch circuit protection for 120/240VAC QO panelboards with Class A 6mA ground fault sensing. If the circuit requires branch circuit overcurrent protection plus personnel ground fault protection in a QO load center, the QO GFCI breaker is the device that does it.
11) For a 3-pole feeder instead of a 2-pole branch circuit, what should I look at?
The Square D QO ground fault breaker is a 2-pole configuration and occupies two spaces in a QO load center, so it will not serve a 3-pole feeder. For three-pole applications the ABB A2A150TT is an A2 Series 3-pole molded case breaker, the ABB TEB is an E150 Series 3-pole thermal magnetic breaker, and the ABB MBB33 is an XT4 Series 3-pole molded case breaker kit. None of those include the Class A 6mA personnel ground fault function the QO GFCI breaker provides.
12) Is the QO GFCI breaker suitable for outdoor or damp location circuits?
The breaker itself mounts inside the load center, but it's intended for ground fault protection of circuits serving wet and damp locations, which is where the Class A 6mA sensing is required. Protect the panel enclosure to the environment it sits in.
