Plug-On Neutral Design
These breakers use a plug-on neutral connection for compatible electrical distribution equipment.
The plug-on neutral design connects to the approved neutral system in compatible load centers and eliminates the traditional neutral pigtail used by standard pigtail-style arc fault breakers.
Confirm that the exact load center is specifically designed for the plug-on neutral breaker configuration before ordering.
Arc Fault Protection
Both models provide arc-fault circuit protection for compatible branch circuit applications.
Arc-fault circuit breakers are designed for applications where arc-fault protection is required. The exact breaker must be matched to the branch circuit rating, electrical equipment, and applicable installation requirements.
15A vs. 20A
THQL1115PAF2 – 15A
The THQL1115PAF2 is the 15A plug-on neutral arc fault configuration.
THQL1120PAF2 – 20A
The THQL1120PAF2 is the 20A plug-on neutral arc fault configuration.

- Verify the required branch circuit ampere rating before installation.
- Confirm system voltage and complete breaker ratings.
- Verify conductor material and wire size requirements.
- Confirm neutral and branch circuit conductor routing requirements.
- Follow ABB terminal and torque requirements.
- Do not substitute a standard breaker where arc-fault protection is required.
- Do not substitute a pigtail-style breaker unless the equipment and application specifically permit it.
- Confirm AFCI requirements with current applicable electrical codes.
- Maintain required electrical working clearances.
- De-energize equipment before installation or service.
- Verify absence of voltage before working inside electrical equipment.
- Installation and service should be performed by qualified electrical personnel.
- Follow current ABB instructions, equipment labeling, and applicable local and national electrical codes.
