Overview
The Eaton CHFN120DF is a 20 A, single-pole CH dual-function circuit breaker for 120 V branch circuits in compatible 120/240 V AC Eaton CH load-center systems. It combines AFCI and GFCI functions with thermal-magnetic overcurrent protection, plug-in mounting, a pigtail neutral, and a 10 kA interrupting rating.
Key Features
-
Dual-function protection: Combines arc-fault and ground-fault protection in one exact-MPN CH breaker.
-
Pigtail-neutral connection: Uses plug-in mounting with box-lug and pigtail-neutral connections for compatible CH equipment.
-
CH compatibility: Intended for Eaton CH load centers specifically listed to accept CHFN120DF.
-
System application: The one-pole breaker protects a 120 V line-to-neutral branch in a compatible 120/240 V AC system.
