Leviton LB120-DFT 20A 1-Pole Plug-On AFCI/GFCI Circuit Breaker White

Description

Product Overview

The Leviton LB120-DFT is engineered to meet the demanding safety standards of modern residential electrical systems while offering a streamlined installation experience. Featuring a 20‑amp rating and a 1‑pole configuration, this plug‑on breaker integrates both arc‑fault circuit interrupter (AFCI) and ground‑fault circuit interrupter (GFCI) technologies into a single, compact unit. Its white finish blends seamlessly with most panel interiors, and the thermal‑magnetic design ensures reliable tripping performance under overload conditions.

Beyond its dual‑function protection, the LB120-DFT incorporates Leviton’s patented reset lockout mechanism, which prevents the breaker from resetting if a fault persists, thereby reducing the risk of repeated trips and potential fire hazards. The unit’s dimensions—3.1 x 1 x 3.9 inches—and lightweight construction (6.72 ounces) make it an ideal fit for tight panel spaces, while the clear LED indicators provide immediate visual feedback on the type of fault detected, even after the breaker has tripped.

Manufactured by Leviton, a trusted name in electrical components, the LB120-DFT carries a strong reputation for durability and performance. It has earned a high customer rating of 4.6 out of 5 stars from 69 reviews, reflecting consistent satisfaction among electricians and DIY homeowners alike. The breaker’s design also supports future upgrades, allowing electricians to wire the entire load center at rough‑in without needing to install individual breakers first, which can save valuable time on large projects.

Usage

This breaker is perfectly suited for a variety of residential applications, including new construction, remodels, and upgrades to existing panels. Homeowners looking to enhance the safety of kitchens, bedrooms, living areas, and home offices will benefit from the combined AFCI and GFCI protection, which guards against both arc‑fault and ground‑fault hazards. The plug‑on design simplifies the installation process, allowing electricians to snap the breaker into place without the need for additional wiring tools or complex adjustments.

In addition to standard residential use, the LB120-DFT can be employed in light commercial settings where code compliance requires both AFCI and GFCI protection on dedicated circuits. Its intuitive LED status indicators help maintenance personnel quickly diagnose issues, reducing downtime and service costs. The breaker’s robust construction also ensures reliable operation in environments with temperature fluctuations and occasional power surges.

For DIY enthusiasts, the clear labeling and straightforward mounting process make the LB120-DFT an approachable choice. The breaker’s safety features, such as the reset lockout and fault‑type LEDs, provide an added layer of confidence for users who may not have extensive electrical training, while still meeting the rigorous standards set by the National Electrical Code (NEC).

FAQ

What is the difference between AFCI and GFCI protection?

AFCI (Arc‑Fault Circuit Interrupter) detects dangerous arcing conditions that can cause fires, while GFCI (Ground‑Fault Circuit Interrupter) protects against electrical shock by detecting imbalances between hot and neutral conductors. The LB120‑DFT combines both, offering comprehensive safety for residential circuits.

Can this breaker be installed in existing panels?

Yes, the LB120‑DFT is designed for retrofit applications. Its plug‑on mounting style fits standard panel slots, and the reset lockout feature works with existing wiring configurations, making it a versatile upgrade option for older panels.

How do the LED indicators work after the breaker trips?

When a fault occurs, the corresponding LED illuminates and remains lit even after the breaker has tripped. This visual cue helps identify whether the issue was an arc fault, ground fault, or overload, allowing faster diagnosis and repair.

Is the breaker compatible with smart home panels?

The LB120‑DFT can be used in panels that support plug‑on breakers, including many smart home‑ready load centers. However, it does not include built‑in communication protocols; it focuses on core safety functions while remaining compatible with external monitoring devices.

What warranty does Leviton provide for this product?

Leviton offers a limited warranty covering defects in materials and workmanship for a period specified in the product documentation. Customers can contact Leviton’s support team for warranty claims or replacement parts.
