ABB THQB 2-Pole GFT Circuit Breaker, 10kA, 240V

The ABB THQB Series is part of ABB's Q Line of circuit breakers — compact, one-inch-wide-per-pole thermal-magnetic devices engineered for residential and commercial load center and lighting panel applications. This GFT (ground fault trip) configuration is built as a 2-pole breaker with a 10kA interrupting rating at 1/240V, combining dependable overcurrent protection with ground-fault sensing in the same compact Q Line footprint. The THQB Series is available across a range of Motor FLA ratings from 15A to 30A, letting installers match the correct breaker to the connected load while keeping the same 2-pole, 10kA, 240V platform and Q Line panel compatibility. Like the rest of the Q Line family, the THQB breaker is designed for straightforward installation into compatible load centers while maintaining the safety and reliability professionals expect from ABB electrical distribution products.

Key Features

  • Configuration: 2-pole design for connection to compatible load centers and lighting panels.
  • Ground Fault Trip (GFT): Integrated ground-fault trip function for enhanced circuit protection beyond standard overcurrent devices.
  • Interrupting Rating: 10kA rating for reliable fault-current interruption in residential and commercial systems.
  • Voltage Rating: Rated 1/240V for standard single-phase branch circuit applications.
  • Motor FLA Range: Available in Motor FLA ratings of 15A, 20A, and 30A to suit a range of connected motor loads on the same platform.
  • Quick-Make / Quick-Break Mechanism: Ensures fast, positive contact action for improved safety and performance.
  • Common Trip Bar: All poles trip together to fully de-energize the circuit on a fault condition.
  • Trip Indication: Easy-to-spot trip indicator simplifies troubleshooting and breaker status checks.
  • One-Inch-Per-Pole Design: Compact Q Line profile for efficient use of panel space.

ABB THQB2130GFT – Frequently Asked Questions

1) Will an ABB THQB GFT breaker fit in my existing load center?
The THQB is part of ABB's Q Line, built one inch wide per pole, so a 2-pole unit occupies two standard 1-inch panel spaces. It plug-mounts into compatible load centers and lighting panels. Confirm the panel is labeled for Q Line / THQB breakers before you buy, since plug-on breakers are only listed for the panels their manufacturer classifies them into.
2) What does the GFT suffix on a THQB breaker actually mean, and is it the same as a GFCI breaker?
GFT is ground fault trip. The breaker adds ground-fault sensing on top of thermal-magnetic overcurrent protection, and all poles trip together on the common trip bar so the circuit is fully de-energized. Equipment ground-fault protection and personnel-level GFCI protection are different trip thresholds, so if your drawing calls for personnel protection specifically, verify the required sensitivity against the spec sheet before you commit.
3) What is the difference between the ABB THQB GFT breaker and a Square D C60 DIN rail breaker?
They mount in completely different ways. The ABB THQB Series is a Q Line plug-in thermal-magnetic breaker, one inch wide per pole, that installs into compatible load centers and lighting panels, and the GFT versions add a ground fault trip function to the overcurrent protection. The Square D C60 UL489 miniature circuit breaker is a DIN rail mount device, so it belongs in an enclosure or control panel fitted with DIN rail rather than in a residential or commercial load center bus. If the opening is a load center interior with a stab bus, the THQB is the form factor that fits; if you are building out a control panel on rail, the C60 is the one to look at.
4) The panel is a Square D I-Line panelboard - can I use the ABB THQB GFT there?
No. The ABB THQB is a Q Line plug-in breaker sized one inch per pole for compatible load centers and lighting panels, and it does not interface with an I-Line bus. For an I-Line panelboard, the Square D PowerPacT Q I-Line circuit breaker is the device built for that connection. Match the breaker to the panelboard bus system rather than to the ampere rating alone.
5) What amperages does the ABB THQB 2-pole GFT breaker come in?
Three ratings: 15A, 20A and 30A, ordered as THQB1115GFT, THQB2120GFT and THQB2130GFT. All carry the same 10kA interrupting rating at 240V.
6) Can I use a 2-pole THQB GFT on a 120V circuit?
It is rated 1/240V, meaning single-phase 120/240V service. A 2-pole device lands on both hot legs for a 240V load, or a 120/240V multiwire circuit. For a straight 120V single-hot branch circuit you want a 1-pole breaker, not this one.
7) I'm standardizing breakers across a building. Is the THQB a DIN rail breaker?
No. The THQB is a plug-on load center breaker with a one-inch-per-pole Q Line profile, not a DIN rail device. If your panel or control enclosure uses a DIN rail, look at a miniature circuit breaker such as the Square D C60 UL489 DIN rail mount instead.
8) What alternatives should I look at if the THQB won't work for my application?
For panelboard branch protection at I-Line style distribution, the Square D PowerPacT Q I-Line breaker is the different mounting class. For DIN rail control panels, the Square D Multi9 C60 1-pole C-curve at 120V AC or the C60 UL489 covers that. For larger molded case work, PowerPacT B. None of those are drop-in replacements for a Q Line plug-on breaker; they are different mounting systems.
9) I only need single-pole protection on a 120V circuit - what should I use instead of the 2-pole ABB THQB?
The ABB THQB GFT breakers described here are built as 2-pole devices rated 240V, so they are intended for two-pole branch circuits rather than a single 120V leg. For a single-pole 120V application, the Square D Multi9 C60 1-pole C-curve miniature circuit breaker is rated 120V AC in a one-pole configuration. Note that the Multi9 C60 is a miniature circuit breaker in the C60 family rather than a plug-in Q Line device, so confirm your panel or rail accepts it before ordering.
10) Is a Square D PowerPacT B a substitute for the ABB THQB 2-pole breaker?
They are not interchangeable. The ABB THQB is a compact Q Line branch breaker, one inch per pole, that plugs into load centers and lighting panels for branch circuit protection at 240V. The Square D PowerPacT B is a molded case thermal magnetic circuit breaker, a larger frame device typically used for feeder and equipment protection and mounted by its own means rather than stabbed onto a load center bus. Use the THQB where you are filling branch positions in a panel; look at the PowerPacT B frame when the application calls for a molded case breaker.
11) How do I tell if a THQB breaker has tripped versus been switched off?
The THQB carries a trip indicator on the handle so a tripped breaker reads differently from one turned off deliberately. That matters on a GFT device, where a ground fault and an overload look the same from the panel door otherwise. Quick-make/quick-break contact action means the handle position is a positive indication, not a partial contact state.
12) Is the THQB GFT suitable for a commercial lighting panel or only residential?
Both. ABB positions the Q Line THQB for residential load centers and commercial lighting panel applications, including branch circuits that need ground fault protection in renovation and new construction work. The limiting factor is the 10kA interrupting rating and the panel's classification, not the building type.
13) If I do not need ground fault sensing, does the ABB THQB still make sense?
The THQB versions covered here are the GFT configuration, meaning ground fault trip sensing is built into the breaker alongside the thermal-magnetic overcurrent protection, and they are offered at 15A, 20A and 30A. That added function is not something you switch off, so if the circuit calls only for straight overcurrent protection you would be specifying more breaker than the job needs. For a plain thermal magnetic device in a different frame class, the Square D PowerPacT B is a thermal magnetic circuit breaker, though it is a molded case product rather than a one-inch plug-in, so verify it suits your enclosure.
