Description
Engineered for commercial applications, the Eaton QB1020AF provides branch/feeder arc fault mitigation. This 20-amp, single-pole breaker operates at 120VAC and mounts securely into Eaton Pow-R-Line panelboards using a standard bolt-on connection. Equipped with a pigtail neutral, this unit ensures accurate fault detection. While superseded by the combination-type QB1020CAF for newer code cycles, it remains available for exact replacements. Rated at 10kAIC, it meets UL 1699 and UL 489 standards.Specifications

Product FAQs
6 answersCan I install the QB1020AF in a standard residential load center?
No. The QB1020AF is a bolt-on miniature circuit breaker designed specifically for commercial Eaton Pow-R-Line panelboards. It is not compatible with standard residential plug-on load centers.
Which panelboards are approved for use with the QB1020AF?
This breaker is UL listed for installation in Eaton Pow-R-Line panelboards, such as the PRL1X and PRL2X series, that accept Quicklag bolt-on breakers.
What is the difference between the QB1020AF and the QB1020CAF?
The QB1020AF provides branch/feeder arc fault protection, while the QB1020CAF is a combination arc fault circuit interrupter that detects both series and parallel arcs. The QB1020CAF supersedes the QB1020AF for newer code cycles, though the QB1020AF remains available for exact replacements.
Is there a higher interrupting rating available for this breaker?
Yes. If your panel requires a higher interrupting capacity, the QBH1020AF offers the same physical footprint and arc fault protection but features a 22kAIC rating.
How is the pigtail neutral on the QB1020AF connected?
The coiled white pigtail wire must be connected directly to the panelboard neutral bus bar to power the internal arc fault detection circuitry.
What type of arc fault protection does the QB1020AF provide?
This breaker provides branch/feeder arc fault protection, which is designed to detect and mitigate high-energy parallel arcing faults in the electrical circuit.
