Abb THQL1120PAF2 Afci Breaker 20 Amp 1 Pole Plug-on Neutral

Product Description

The ABB THQL1120PAF2 is a 1-pole, 20-amp arc fault circuit interrupter (AFCI) breaker with plug-on neutral (PON) design and a 10,000 AIC interrupting rating. AFCI breakers detect and respond to dangerous arcing conditions in branch circuits, providing a layer of protection beyond standard overcurrent devices. This breaker is installed by licensed electricians in residential and light commercial panel applications where AFCI protection is required by code. The plug-on neutral feature eliminates the need for a separate neutral pigtail wire, simplifying installation in compatible load centers.

This breaker is suited for 120-volt branch circuits in residential construction and renovation projects. It is commonly installed in bedroom circuits, living areas, and other locations where the National Electrical Code (NEC) mandates AFCI protection. Electricians working in new construction or panel upgrades will find the PON configuration reduces installation time in compatible load centers that support plug-on neutral breakers.

Key Features

• 20-amp, 1-pole AFCI protection for 120-volt branch circuits
• 10,000 AIC interrupting rating for residential and light commercial use
• Plug-on neutral (PON) design eliminates separate neutral pigtail
• Meets NEC AFCI protection requirements for applicable circuits
• Detects parallel and series arcing conditions to reduce fire risk

Compatibility

Designed as an OEM-style replacement AFCI breaker for residential and light commercial load centers that accept plug-on neutral single-pole breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and all applicable local codes. De-energize the load center and verify the absence of voltage before handling any breaker or bus connections. The plug-on neutral design requires a compatible load center with a PON bus rail. Do not attempt to adapt this breaker for use in load centers that do not support plug-on neutral configurations.
