Eaton BRN120A1CS 20A 1P 120V Circuit Breaker, AFCI, GFCI, Dual-Function | AmpState

The Eaton BRN120A1CS is a 20A, 1-pole circuit breaker that combines AFCI and GFCI protection in a single, compact device. Built for everyday electrical work, it protects branch circuits in panelboards, load centers, and electrical distribution systems with a reliable Eaton design you can trust.

• Dual-function protection: Integrated AFCI and GFCI protect against arc faults and ground faults on the same circuit, simplifying wiring and boosting safety.
• Exact part-number match: BRN120A1CS is the precise Eaton replacement you need for compatible panels, making maintenance, stocking, and panel rebuilding straightforward.
• Specifications at a glance: 20 amps, 1-pole, 120 volts—ideal for residential and light commercial circuits requiring AFCI/GFCI protection.
• Trusted brand: Manufactured by Eaton, a longtime leader in electrical protection and distribution equipment.
• Easy sourcing: Available through AmpState, with support to confirm fit and compatibility for your panel system.

Ideal use cases

• New installations or remodels that require combined arc-fault and ground-fault protection on a 120V circuit.
• Retrofits in panelboards or load centers where space and component count matter—one device replaces two separate protections.
• Spare inventory for maintenance teams and panel builders who must match a specific Eaton part number for reliability and warranty.

Why it matters: By delivering AFCI and GFCI protection in one breaker, this device helps simplify panel layouts, reduces the number of components in fault-protection schemes, and supports code compliance requirements for circuits that need both arc-fault and ground-fault protection.

Installation notes: Ensure your Eaton panelboard or load center accepts the BRN120A1CS and that the circuit is intended for 20A, 120V, 1-pole protection. If you’re unsure about compatibility or part-number matching, AmpState can assist with fit verification and listing details.
