ABB THQL Series Plug-On Neutral Ground Fault Circuit Breaker, 10kAIC

The ABB THQL Series Plug-On Neutral Ground Fault Circuit Breaker delivers dependable ground fault protection for residential and light commercial panelboards. This family is available in 1-Pole and 2-Pole configurations at 15A, 20A, and 30A ratings, giving electrical professionals the flexibility to match branch circuit protection to specific load requirements while every option shares a common Plug-On Neutral (PON) design and a 10kAIC interrupt rating for consistent, dependable performance under fault conditions. Designed to integrate with compatible THQL-type panelboards, the breaker simplifies loadcenter installation by eliminating the pigtail neutral wiring typically required in traditional breaker installs, reducing labor time on both new construction and panel upgrade jobs. Whether the application calls for a single-pole 15A circuit or a two-pole 30A circuit, the THQL Series platform delivers the same reliable ground fault monitoring and 10kAIC interrupt performance across the entire lineup.

Key Features

  • Plug-On Neutral (PON) Design: Simplifies wiring and installation in compatible panelboards, reducing labor time across every pole and amperage configuration.
  • Ground Fault Protection: Monitors circuits for ground fault conditions to help reduce shock and fire hazards on the branch circuits it protects.
  • Interrupt Rating: Rated 10kAIC across the full THQL Series lineup for dependable performance during fault conditions.
  • THQL Series Compatibility: Engineered to fit THQL-type loadcenters and panelboards for straightforward replacement or new installation.
  • Configuration Range: Available in 1-Pole and 2-Pole configurations at 15A, 20A, and 30A ratings to match specific circuit protection needs.
  • Compact Molded Case: Space-efficient design supports standard panelboard layouts without modification, regardless of pole count or amperage selected.

ABB THQL1120PGFT – Frequently Asked Questions

1) Will an ABB THQL Plug-On Neutral GFCI breaker fit my existing THQL load center?
The THQL Series ground fault breaker is built to fit THQL-type loadcenters and panelboards, so it drops into a panel already using THQL breakers for either a replacement or a new circuit. The catch is the Plug-On Neutral design: it picks up the neutral through the panel's PON bus rather than a pigtail, so the panel has to be a plug-on neutral loadcenter for that feature to work. Older THQL panels without a PON bus take standard pigtail GFCI breakers instead.
2) What amperages and pole counts does the ABB THQL PON ground fault breaker come in?
Six configurations: 1-pole in 15A, 20A and 30A (THQL1115PGFT, THQL1120PGFT, THQL1130PGFT), and 2-pole in 15A, 20A and 30A (THQL2115PGFT, THQL2120PGFT, THQL2130PGFT). Pick the 1-pole for a 120V branch circuit and the 2-pole for a 240V load such as a water heater, spa or well pump.
3) Is this a GFCI breaker or an AFCI breaker?
Ground fault only. The THQL PGFT breakers monitor the circuit for ground fault conditions to cut shock and fire risk, which is what you want on bathroom, kitchen, garage, outdoor and pool or spa circuits. Where the code calls for arc fault protection, bedrooms and most living-area circuits, a GFCI breaker will not satisfy it; you need an AFCI or a dual-function device.
4) Will a Square D Multi9 C60 breaker fit in a THQL loadcenter instead of an ABB THQL ground fault breaker?
No. The ABB THQL Series Plug-On Neutral Ground Fault Circuit Breaker is built to plug into THQL-type loadcenters and panelboards, seating on the panel's plug-on neutral bar. The Square D C60 UL489 Miniature Circuit Breaker is a DIN rail mount device, so it mounts on a rail inside an enclosure or control panel rather than onto a loadcenter bus stab. The two are different mounting systems and are not interchangeable in the same enclosure.
5) Why order the plug-on neutral version instead of a pigtail GFCI breaker?
Labor, mostly. A PON breaker makes its neutral connection when it snaps onto the bus, so there is no white pigtail to route and land on the neutral bar. On a panel change or a multi-circuit AFCI/GFCI retrofit that saves real time per breaker and leaves the gutter cleaner. The trade-off is that the panel must have the plug-on neutral bus; in a panel that does not, the pigtail style is what you need.
6) I need a 240V GFCI breaker for a hot tub feed. Which one of these do I order?
Take a 2-pole. THQL2130PGFT covers a 30A 240V spa feed, with 2-pole 20A (THQL2120PGFT) and 2-pole 15A (THQL2115PGFT) available if the equipment nameplate calls for less. Size to the manufacturer's stated maximum overcurrent device, not to the breaker you happen to have. All three carry the same 10kAIC interrupt rating.
7) Does this breaker take up two spaces in the panel?
A 1-pole THQL ground fault breaker occupies one full-size panel space and a 2-pole occupies two adjacent spaces on opposite bus legs. The molded case is sized for standard panelboard layouts, so no modification to the load center is needed. Worth counting your free spaces first: swapping a standard 1-pole for a 2-pole GFCI means finding a second adjacent slot.
8) What should I use for a feeder or larger service application rather than the ABB THQL GFCI breaker?
Look at a molded case breaker. The Square D PowerPacT B is a thermal magnetic circuit breaker and the Square D PowerPacT Q is an I-Line circuit breaker, both molded case designs used where branch plug-in breakers do not apply. The ABB THQL Series Ground Fault Circuit Breaker is a branch circuit device offered in 1-pole and 2-pole configurations at 15A, 20A and 30A for residential and light commercial panelboards.
9) How does this ABB breaker come packed for a multi-unit or property job?
Each THQL PGFT ground fault breaker is packed 1 EA, so quantities scale one-for-one with the number of circuits you are protecting. Handy when you are spec'ing a fixed count across a building of identical units rather than buying by the carton.
10) I have a federal job with Buy American requirements. Is this ABB breaker BAA compliant?
ABB's position on both Buy American Act and ARRA compliance for the THQL PGFT breakers is contact manufacturer, and the country of origin on record is unknown. For a project where domestic content is a contract condition, get written confirmation from ABB tied to the specific part number before it goes on the submittal.
