ABB TQO Residential Plug-In Circuit Breaker

The ABB TQO Residential Plug-In Circuit Breaker is a 120/240 V overcurrent protection device engineered for plug-in installation in compatible residential and light commercial load centers. The TQO series is available in 20, 30, and 60 ampere ratings, with 1-pole and 2-pole configurations, giving electricians and contractors a flexible platform for sizing branch-circuit protection to the load. Its plug-in design allows the breaker to be installed directly onto the panelboard bus without additional hardware, making the TQO series a practical choice for panel upgrades, breaker replacements, and new residential construction. Regardless of the amperage or pole count selected, every TQO breaker shares the same 120/240 V rating and plug-in mounting style, delivering consistent, code-compliant switching and interruption across the family.

Key Features

  • Amperage Options: Available in 20A, 30A, and 60A ratings to support a range of residential branch-circuit loads, from lighting and receptacle circuits to sub-panels and dedicated equipment circuits.
  • Pole Configurations: Offered in 1-pole and 2-pole configurations to match single-phase residential and light commercial circuit requirements.
  • Voltage Rating: 120/240 V rating matches standard single-phase residential and light commercial panelboard systems across every amperage and pole option.

ABB TQ1120 – Frequently Asked Questions

1) What amperages and pole counts can I get in the ABB TQO plug-in breaker?
Three ABB TQO breakers are offered: a 1-pole 20 amp (TQ1120), a 1-pole 30 amp (TQ1130), and a 2-pole 60 amp (TQ2160). All are plug-in style rated 120/240V. If you need a 240V circuit for a sub-panel, range, or AC condenser, the 60 amp TQ2160 is the 2-pole unit; the 20 and 30 amp units are single pole for 120V branch circuits.
2) Will an ABB TQO breaker fit my load center, or do I need a bolt-on breaker?
The TQO is a plug-in breaker, so it clips straight onto the panelboard bus in a load center built to accept the TQO plug-in format, with no mounting hardware. It will not work in a panel that requires bolt-on breakers, where the breaker is screwed to the bus. Check the label inside your panel door for the accepted breaker types before ordering.
3) Can I use a 60 amp ABB TQO breaker to feed a sub-panel?
Yes. The 2-pole 60 amp TQO (TQ2160) is rated 120/240V, which is what a single-phase sub-panel feeder needs, and the description calls out sub-panels and dedicated equipment circuits as typical uses. Size the feeder conductors and the sub-panel main lugs to the 60 amp rating.
4) I need a DIN rail breaker for a control panel. Does the ABB TQO work?
No. The TQO is a plug-in load center breaker that seats on a panelboard bus, not a DIN rail device. For a DIN rail control or equipment panel, look at the Square D C60 UL489 miniature circuit breaker, which is DIN rail mount, or the Multi9 C60 1-pole C-curve MCB rated 120V AC.
5) What should I use instead of an ABB TQO breaker if my panel is DIN rail rather than a plug-in load center?
The ABB TQO breaker is a plug-in device that seats directly on the panelboard bus of a compatible load center, so it will not mount to a DIN rail. For a DIN rail installation, the Square D C60 UL489 miniature circuit breaker is a DIN rail mount MCB and is the right form factor for that enclosure. Confirm the amperage and voltage you need are available in the C60 before ordering, since the mounting method is the deciding difference here.
6) Is the Square D Multi9 C60 1-pole breaker a substitute for an ABB TQ1120 20A single-pole?
They are not interchangeable in the same panel. The ABB TQ1120 is a 20A single-pole breaker in the TQO plug-in format, meant to clip onto the bus of a load center that accepts TQO. The Square D Multi9 C60 1-pole is a miniature circuit breaker rated 120V AC on the C-curve, built for a different mounting arrangement. Both are single-pole devices, but the bus interface differs, so match the breaker to the panel you actually have rather than to the amperage alone.
7) For a light commercial feeder instead of a residential branch circuit, what is an alternative to the ABB TQ2160 two-pole 60A?
The ABB TQ2160 is a two-pole 60A plug-in breaker rated 120/240V, sized for residential and light commercial load centers, sub-panels, and dedicated equipment circuits. Where the application calls for a molded case device rather than a plug-in residential breaker, the Square D PowerPacT B is a thermal magnetic circuit breaker, and the PowerPacT Q is an I-Line circuit breaker for I-Line panelboards. The choice comes down to the panel type: TQO for a plug-in load center, PowerPacT Q where the distribution equipment is I-Line.
8) Is the ABB TQO breaker suitable for a commercial panelboard or just houses?
The TQO series is a residential-duty plug-in breaker, and the 120/240V rating covers standard single-phase residential and light commercial load centers. For 3-phase distribution gear or higher interrupting duty you want a molded case device instead, such as the Square D PowerPacT B thermal magnetic breaker or the PowerPacT Q I-Line breaker.
9) Which ABB TQO breaker do I order for a standard 120V lighting or receptacle circuit?
Take a single-pole unit: TQ1120 for a 20 amp circuit or TQ1130 for 30 amps. Single-pole TQO breakers land on one bus leg for 120V. The 60 amp TQ2160 is 2-pole and spans both legs for 240V loads, so it is the wrong choice for general lighting and receptacles.
10) Can I use an ABB TQO to replace a failed breaker in an existing panel?
That is one of its main uses. The TQO is a drop-in style replacement for any panel that accepts the TQO plug-in format, so swapping a tripped or damaged breaker is a matter of pulling the old one off the bus and seating the new one. Match the amperage and pole count of the breaker you are removing: 20 or 30 amp single pole, or 60 amp two pole.
11) What looks like an ABB TQO equivalent but will not drop into a TQO load center?
Several breakers carry similar amperage ratings without sharing the TQO plug-in bus connection. The Square D PowerPacT B thermal magnetic breaker and the PowerPacT Q I-Line breaker are molded case devices built around different mounting systems, and the Square D C60 is a DIN rail mount MCB. None of these clip onto a TQO bus stab. For a straight replacement in a panel that accepts the TQO format, stay within the TQO series - TQ1120 for 20A single-pole, TQ1130 for 30A single-pole, or TQ2160 for 60A two-pole.
12) How are ABB TQO breakers packaged for stocking?
Each TQO breaker ships 1 EA, so you order by the piece rather than a multi-pack. That suits an MRO crib or a service truck where you want a couple of each amperage on the shelf for replacements.
