Overview
The Eaton Cutler-Hammer CHEP120A1CS is a 20 Amp, single-pole, dual-function circuit breaker from Eaton's Type CH residential series. It combines Arc Fault Circuit Interrupter (AFCI) and Ground Fault Circuit Interrupter (GFCI) protection in one compact unit, designed to safeguard against electrical fires, shocks, and overloads in homes, apartments, or light commercial settings. The "PON" in the query likely refers to "Plug-On Neutral," a key feature allowing direct connection to the neutral bus without pigtail wiring, simplifying installation in load centers. This model is an enhanced version of earlier dual-function breakers like the CHFAFGF120, with improved electronics for fewer nuisance trips. Released as part of Eaton's premium CH lineup (updated around 2020), it's UL-listed, meets NEC requirements for bedrooms and kitchens, and fits Eaton CH panels (200A main breaker compatible). It's ideal for branch circuits powering outlets, lights, or appliances up to 20A.
Key Features
Protection Types:
AFCI: Detects dangerous arcing faults (e.g., from damaged wires) that could cause fires.
GFCI: Senses ground faults (e.g., water contact) to prevent shocks, with a 5mA trip threshold.
Dual-function means one breaker handles both—no need for separate devices.
Ratings: 20A at 120V AC; 10kAIC (kiloamp interrupting capacity) for short-circuit protection; thermal-magnetic trip mechanism for overloads.
Design: Plug-On Neutral (PON) for easy snap-in installation; VISI-Trip flag (red indicator) shows if tripped vs. manually off; white thermoplastic housing for a clean look.
Compatibility: Works with Eaton CH load centers, NEMA 1/3R enclosures; supports LED/CFL/incandescent loads; no neutral pigtail required.
Durability: Rated for 10,000 operations; operates in -40°F to 185°F; V-2 flame-retardant materials.
Installation
This breaker installs quickly in Eaton CH panels: Snap it onto the bus bar (plug-on tabs connect hot and neutral directly), wire the line (14–4 AWG copper/aluminum) to terminals, and connect load wires. No additional neutral wire needed, reducing callbacks. Requires a 120V circuit; test monthly via the built-in button. Full setup takes 5–10 minutes for pros; DIYers should consult an electrician to ensure code compliance (e.g., NEC 210.12 for AFCI). Includes wear-resistant label for circuit identification.
