ABB THQL11 Series 1-Pole Arc Fault Circuit Breaker

The ABB THQL11 Series Arc Fault Circuit Breaker is a 1-pole (1P) branch circuit breaker built for combination arc-fault (AFCI) circuit protection in THQL11 series plug-on neutral (PON) load centers. This family is available with a Choose Amperage Rating option spanning 15A to 20A, allowing electricians to match the breaker to the branch circuit load while retaining a shared 10kAIC interrupt rating across every option. Designed for reliable overcurrent and arc-fault protection, this breaker is a common replacement or add-on unit for residential and light commercial panelboards using the THQL11 platform. Each unit ships individually packaged for straightforward stocking and installation.

Key Features

  • Pole Configuration: 1-Pole (1P) design for single branch-circuit protection.
  • Amperage Rating Options: Choose from 15A or 20A ratings, suited to standard residential and light commercial branch circuits.
  • Interrupt Rating: 10kAIC interrupting capacity for dependable fault-clearing performance across the amperage range.
  • Arc Fault Protection: Combination Arc Fault (AFCI) protection helps guard against fires caused by arcing conditions in branch wiring.
  • PON Compatibility: Plug-On Neutral (PON) configuration matched to the THQL11 series load center platform.
  • Series Platform: Part of the ABB THQL11 Series of molded-case circuit breakers.
  • Individually Packaged: Ships as a single unit for easy stocking, replacement, and field installation.

ABB THQL1115PAF2 – Frequently Asked Questions

1) Will an ABB THQL1115PAF2 arc fault breaker plug into my existing THQL load center?
The THQL11 Series AFCI is built as a plug-on neutral (PON) breaker matched to THQL11 series load centers. That means the panel has to have a plug-on neutral bus. If your panel is an older THQL load center with a conventional neutral bar and no PON bus, this breaker will not land correctly, and you need a pigtail-style AFCI instead.
2) Is this ABB breaker a combination AFCI or a dual-function AFCI/GFCI?
It is a combination arc fault device (AFCI) only. It provides branch circuit overcurrent protection plus arc-fault detection. It does not include ground fault protection for personnel, so on an opening that also requires GFCI, such as a kitchen or laundry receptacle circuit, you need a dual-function breaker or a downstream GFCI receptacle.
3) Can I use the ABB THQL11 AFCI to upgrade an existing standard breaker for arc fault protection?
That is one of its intended uses. It is sold as a replacement or add-on for residential and light commercial panelboards on the THQL11 platform, including arc-fault safety upgrades in existing panels. The one thing to confirm is that the panel is a plug-on neutral THQL11 load center, since the breaker's neutral connection depends on that bus.
4) Can a Square D Multi9 C60 breaker be used in place of an ABB THQL1115PAF2 in a THQL11 load center?
No. The ABB THQL11 Series 1-pole arc fault breaker is a plug-on neutral (PON) unit built to seat on the bus and neutral bar of THQL11 series load centers. The Square D Multi9 C60 is a 1-pole C-curve miniature circuit breaker rated 120V AC, a DIN-rail style device that has no plug-on neutral stab and does not mount to a THQL11 panel bus. For an arc fault branch circuit in a THQL11 panel, stay with the THQL1115PAF2 at 15A or the THQL1120PAF2 at 20A.
5) What amperages does the ABB THQL11 plug-on neutral AFCI breaker come in?
Two: 15A (THQL1115PAF2) and 20A (THQL1120PAF2). Both are single pole. 15A covers standard lighting and general receptacle circuits, 20A covers the higher-load branch circuits like kitchen and laundry receptacles.
6) Does the THQL11 AFCI need both the hot and neutral of the branch circuit landed on it?
Yes. An AFCI monitors the complete circuit, so the branch neutral has to terminate on the breaker rather than on the panel neutral bar. On this plug-on neutral design the panel-side neutral is made automatically when the breaker clips onto the PON bus, so you only land the circuit hot and the circuit neutral on the breaker terminals. Shared or multiwire neutrals have to be separated first.
7) What is the difference between the ABB THQL11 AFCI breaker and a Square D C60 UL489 MCB?
They are different mounting platforms and different protective functions. The ABB THQL11 Series breaker is a 15A or 20A 1-pole unit with combination arc-fault (AFCI) protection and a 10kAIC interrupting rating, designed to plug into THQL11 series plug-on neutral load centers. The Square D C60 is a UL489 miniature circuit breaker that mounts on DIN rail, which suits control panels and equipment enclosures rather than a residential or light commercial panelboard. Choose by how the enclosure is built: DIN rail chassis takes the C60, THQL11 panel bus takes the ABB unit.
8) I need overcurrent protection for a feeder, not a branch circuit. Is the ABB THQL11 AFCI the right breaker?
No. The ABB THQL11 Series 1-pole arc fault breaker is a branch circuit device at 15A or 20A, intended for residential and light commercial branch wiring in THQL11 plug-on neutral panelboards. For larger molded-case feeder or main applications, the Square D PowerPacT B thermal magnetic circuit breaker or the Square D PowerPacT Q I-Line breaker are the molded-case platforms to look at, the I-Line version for bolt-on I-Line panelboard mounting.
9) Is this ABB AFCI breaker sold individually or in a multi-pack?
Each unit ships individually packaged, which is what you want if you are stocking a truck or a maintenance crib and pulling one or two at a time rather than wiring a whole panel.
10) Is there a simpler ABB THQL11 option if the circuit does not require arc fault protection?
Within the ABB THQL11 Series, the PAF2 units are the combination arc-fault versions, offered 1-pole at 15A as THQL1115PAF2 and 20A as THQL1120PAF2, each with a 10kAIC interrupting rating and plug-on neutral construction. If arc fault protection is not being added, a standard THQL11 thermal magnetic breaker of the same amperage seats in the same load center; the PAF2 designation is what identifies the AFCI build, so match that suffix when the circuit requires AFCI coverage.
