Eaton CHFP120DF - 20 A, 120 V, 1-Pole Plug-In Circuit Breaker | AmpState

Meet the Eaton CHFP120DF from AmpState—a compact 20A, 120V, 1-pole plug-in molded case circuit breaker engineered to deliver dependable branch circuit protection in panelboards and load centers. Designed for residential, commercial, and light industrial applications, this unit snaps into compatible OEM panels for fast installation and reliable performance where it matters most.

• Plug-in installation: Fast, secure connection that minimizes downtime when upgrading or replacing a breaker, keeping your panel uptime consistent.
• Thermal-magnetic trip: Delivers stable overload protection with a precise thermal element and an instantaneous magnetic trip for short circuits, reducing the risk of wiring damage and nuisance trips.
• 20A, 120V, 1-pole: Straightforward single-pole protection ideal for standard 120V circuits commonly found in homes, offices, and light industrial spaces.
• Panel compatibility: Specifically designed to be compatible with matching OEM load centers and panelboards, ensuring a seamless fit and reliable performance.
• Versatile applications: A practical choice for branch circuits in electrical panels across residential renovations, commercial rebuilds, and light industrial installations.

How it works: In normal operation, the CHFP120DF remains quiescent until current draw approaches or exceeds 20A. The thermal portion responds to overheating conditions, providing gradual protection during overloads, while the magnetic portion triggers a fast trip on high-magnitude faults. The result is timely interruption of fault currents and preserved wiring insulation and equipment.

Why choose this breaker—and why now:

• Reliable, predictable trip curves across varying temperatures and loads help prevent unwelcome outages in essential circuits.
• Easy replacement in existing panelboards reduces downtime during electrical maintenance or panel upgrades.
• Compatibility with OEM panels means you won’t have to modify or repurpose mismatched hardware—just plug it in and restore protection.
