Eaton Cutler-Hammer CL120AF 20A 1P 120V Circuit Breaker, AFCI | AmpState

The Eaton Cutler-Hammer CL120AF 20A 1P 120V AFCI circuit breaker is built for everyday electrical work, delivering reliable arc-fault protection where it matters most—in panelboards, load centers, and electrical distribution systems. This 1-pole, 120-volt device is designed to simplify retrofit projects and maintenance by keeping the part number consistent, so replacements won’t disrupt your existing wiring or project timelines. AmpState makes it easy to source and verify fit, with direct support to confirm compatibility if needed.

Key features

• AFCI protection detects dangerous arcing in conductors and interrupts power to help prevent electrical fires.
• 20 A, 1-pole, 120 V configuration is a common requirement for branch circuits in many homes and light commercial setups.
• Part number stability ideal for retrofit work and ongoing maintenance where keeping the same part number simplifies ordering and inventory management.
• Panelboard and load center compatibility designed to integrate into standard distribution systems without extensive rework.
• Support from AmpState assistance available to verify fit and ensure you’re choosing the right solution for your panel.

Ideal use cases

• Retrofits in homes upgrading circuits to include AFCI protection while preserving existing part numbers for easy maintenance planning.
• New or existing panelboards and distribution setups where a 1P 120V, 20A AFCI breaker is required.
• Electrical distribution projects where reliability and quick replacement are priorities for ongoing service schedules.

Why this matters

• Arc faults are a common hazard in residential and light commercial circuits. An AFCI breaker like the CL120AF interrupts those faults, reducing the risk of in-circuit fires and enhancing overall electrical safety.
• Maintaining a consistent part number during upgrades minimizes downtime and confusion for maintenance teams, making sustained operations smoother.
• Choosing a trusted brand—Eaton Cutler-Hammer—helps ensure predictable timing for replacements and compatibility with existing Eaton-based electrical infrastructure.
