Leviton LB120-AFT 20 Amp Single-Pole Arc Fault AFCI Circuit Breaker, Plug-On 120V

The Leviton LB120-AFT is a brand new 20 Amp, 1-pole, 120V combination AFCI (arc-fault) circuit breaker for Leviton load centers. It protects your home's wiring from dangerous arcing faults, one of the leading causes of electrical fires, while also giving you standard thermal-magnetic overload and short-circuit protection.

All Plug-On: No Pigtails, No Breaker Wiring

Leviton's all plug-on design means the circuit wires land on the load center, not on the breaker. The breaker simply plugs in. The whole panel can be wired at rough-in before any breakers are installed, and swapping a breaker later takes seconds.

Smart Trip Indicators

Built-in LEDs show that the breaker has tripped and what type of fault caused it, and they stay lit even after the trip. That makes troubleshooting much faster. Leviton's reset lockout also keeps the breaker from resetting if arc-fault protection has been compromised.

Size

1" wide, about 3 7/8" tall, and 3 1/8" deep. It takes one space in a Leviton load center.

Uses

Bedrooms, living rooms, family rooms, hallways, closets, home offices, and other dwelling-unit 20A circuits where AFCI protection is required, wired with 12 AWG copper.

Most Common Use

Adding or replacing a 20A AFCI circuit in a home with a Leviton load center, for new construction, a remodel, or bringing a circuit up to current code.

Important: A 20A breaker must be used with 12 AWG copper wire or larger. Never install a 20A breaker on a circuit wired with 14 AWG wire.

Compatibility: This breaker is designed for Leviton load centers only. It does not fit Square D, Eaton, Siemens, GE, or other brands' panels. Check the label inside your panel door before ordering. If you're unsure, send us a photo of your panel label and we'll help you confirm the fit.
