Leviton LB120-DFT 20A 1-Pole Plug-On AFCI/GFCI Breaker | 120 VAC Safety & Easy Rough-In Install

Overview

The Leviton LB120-DFT is a 20A, 1-pole plug-on AFCI/GFCI breaker designed for residential panels operating at 120 VAC. Built with thermal-magnetic trip technology, it offers dual-function protection intended to address arc faults and ground faults within a compact, easy-to-install module.

During rough-in or panel upgrades, this unit shines with a design that can support wiring the entire Load Center before breakers are installed. This approach can streamline planning and setup, reducing early-stage complexity for both new builds and rejuvenated panels.

Key benefits at a glance

• Dual-function protection combines arc fault and ground fault safeguards in a single unit.
• Reset lockout technology prevents reset if protection is compromised, helping maintain intended protection levels.
• LED indicators communicate trip type and fault conditions, remaining illuminated after a trip to aid quick diagnosis.
• Rocker-style switch requires less activation force, offering smoother operation during panel management.

Daily use and real-world scenarios

With its 120 VAC, 20A rating, this breaker fits standard residential circuits and is designed for compatibility with compatible Leviton Load Centers. The plug-on design aims to simplify replacement and upgrades, keeping panel layouts organized.

In practice, the LEDs and intuitive operation can help you identify fault conditions more quickly and re-energize circuits with confidence after a trip. The compact form factor supports efficient panel density without sacrificing clarity or control.

Why consider this breaker

• Rough-in wiring flexibility reduces early-stage setup effort.
• Visible fault information can save time during service checks.
• A compact, thermal-magnetic solution pairs performance with user-friendly design.
