Feature: 1" width with plug-on mounting and single-pole configuration. Business Impact: Saves panel space and reduces install time, enabling higher panel density and faster wiring. Application: Ideal for compact control panels in industrial environments where space is limited and reliability is critical. Feature: 20 A amperage rating with 120/240 V operating voltage. Business Impact: Delivers appropriate protection for general-purpose circuits while supporting dual-voltage applications common in light commercial spaces. Application: Distribution panels and branch circuits requiring robust GFCI protection. Feature: 10 kAIC interrupt rating. Business Impact: Improves fault current handling and enhances electrical safety by limiting fault energy transfer. Application: Panels near high fault-current sources or in systems with elevated short-circuit potential. Feature: Ground fault circuit interrupter indication (GFI). Business Impact: Provides immediate visual confirmation of ground fault protection status, reducing downtime and uncertainty. Application: Wet locations or equipment with higher shock risk where quick fault identification matters. Feature: Wire size range #14-8 AWG and plug-on connection. Business Impact: Facilitates straightforward wiring with common residential and small commercial conductors, lowering termination errors. Application: Standard branch circuits and small appliance circuits in Eaton-enabled panel systems. Insight: The combination of Trip-to-center operation and compact form factor supports easier compatibility checks during panel retrofits and new installations, while the built-in protection reduces nuisance trips and unplanned downtime in everyday industrial scenarios.

FAQs
Begin by powering down the panel and verifying compatibility with a 1" breaker. Align the CLGF120 with the bus and snap it into the plug-on mounting rails. Connect wires using #14-8 AWG conductors, ensuring correct polarity for the single-pole circuit. Close the panel, reset the breaker, and verify GFI indication. Always consult the Eaton datasheet for torque specs and confirm that the installation adheres to local electrical codes.
Key specs include a 20 A amperage rating, 120/240 V voltage rating, single-pole construction, 10 kAIC interrupt rating, and GFCI (Ground Fault Circuit Interrupter) functionality with GFI indicators. It supports plug-on connection and accepts #14-8 AWG wire. The unit is designed for trip-to-center operation in a compact 1" form factor, suitable for Eaton panel systems.
Yes. The CLGF120 is a plug-on, 1" wide, single-pole GFCI breaker designed for panelboard installations. It accepts #14-8 AWG wiring and provides a 120/240 V supply with a 20 A rating, while delivering up to 10 kAIC fault interruption. This makes it well-suited for compact commercial and light-industrial panels where space is at a premium and ground-fault protection is required.
Certification details vary by region and model configuration; distributors and Eaton provide the official datasheets and catalog numbers. For the CLGF120, refer to the Eaton Specification Sheet and the Standard circuit breaker catalog numbers PDF listed in the downloads. These documents offer the official compliance statements and installation guidance required for UL/CSA/CE considerations in your jurisdiction.
The CLGF120 delivers lower long-term risk of electrical shock and nuisance ground-fault trips, reducing downtime and maintenance labor. Its compact plug-on design accelerates installations and future panel upgrades, potentially lowering labor costs. Regular testing of GFCI functionality and periodic visual inspection of the indicator (GFI) help ensure continued protection and reliability in daily operations.
