Eaton CHFN120GF GFCI Ground Fault Circuit Breaker

The Eaton CHFN120GF is a 20 Amp, 1‑Pole GFCI ground fault circuit breaker designed to protect a single circuit in panelboards that accept CH series breakers. Identified by model CHFN120GF, this device belongs to Eaton’s CH family and is intended for use where CH style protection is installed in compatible Eaton panels. As a GFCI breaker, it monitors current imbalance between conductors and will interrupt power on the protected circuit when a ground fault is detected, helping to reduce the risk of electrical shock. The 20 Amp rating and 1‑pole configuration define its primary electrical characteristics, making it suitable for branch circuits requiring ground-fault protection within an Eaton panel environment. This model provides the essential safety function of a GFCI breaker while maintaining the compact, standardized form factor associated with Eaton’s CH lineup.
