BRN120AF - 20 Amp Circuit Breaker

When it comes to protecting residential electrical circuits, the Eaton BRN120AF goes beyond standard overload and short-circuit protection. This 20 Amp single-pole Combination Type AFCI circuit breaker is designed to detect potentially dangerous arc faults that can occur from damaged wiring, loose connections, or deteriorating electrical components—conditions that may otherwise go unnoticed until they become serious safety concerns.

Built for use in compatible Eaton Type BR loadcenters and panelboards, the BRN120AF combines dependable circuit protection with advanced arc-fault detection in a single, easy-to-install device. Its plug-on design and pigtail neutral connection make it a practical choice for electricians performing panel upgrades, breaker replacements, remodeling projects, or new residential installations. Because it detects both series and parallel arc faults, this breaker helps provide an additional layer of protection for branch circuits serving bedrooms, living rooms, hallways, home offices, and other commonly occupied areas of a home.

Whether you're updating an older electrical system or working on new construction, the Eaton BRN120AF helps support compliance with modern electrical code requirements while delivering the reliable performance expected from Eaton's trusted BR series. Its 10 kAIC interrupting rating makes it a dependable option for protecting residential circuits where code-compliant AFCI protection is required.
