Leviton LB220-AF 20A 2-Pole AFCI Breaker

Designed to safeguard structures and critical systems, the Leviton LB220-AF 20A 2-Pole AFCI breaker provides targeted arc-fault protection that helps prevent electrical fires and protects sensitive security and surveillance equipment. As a Leviton circuit breaker using hydraulic-magnetic trip technology, it maintains precise performance across extreme temperatures while delivering dependable, repeatable trips. The 20A, 2-pole configuration supports 120/240V branch circuits often used for monitoring, access control, and low-voltage power distribution.

Installers and facility managers benefit from the plug-on design that allows rough-in wiring before breakers are installed—reducing labor time on commercial and residential projects. Integrated LEDs clearly indicate trip condition and fault type for fast diagnostics, while patented reset-lockout prevents unsafe resets if ground or arc fault protection is compromised. UL-listed and RoHS compliant, the LB220-AF is built for long-term reliability and is backed by Leviton’s limited warranty.

Ideal for protecting data closets, surveillance systems, alarm panels and other critical infrastructure, this AFCI breaker combines electrical safety with installer-friendly features—choose the LB220-AF to harden your power distribution and order now to secure your installation.
