Leviton LB120-AFT 20A 1-Pole Thermal Magnetic AFCI Branch Circuit Breaker

Protect critical circuits and sensitive equipment with the Leviton LB120-AFT 20A 1-Pole Thermal Magnetic AFCI Branch Circuit Breaker. Designed for contractors and facility managers, this AFCI breaker actively detects and interrupts dangerous arcing faults on 120V branch circuits, reducing fire risk and minimizing downtime for security and surveillance installations. The 20A, 1-pole rating and thermal-magnetic trip deliver dependable overcurrent and short-circuit protection while safeguarding cameras, access control, DVRs/NVRs, and other monitoring equipment.

Installation is faster and cleaner with the plug-on mounting and low-force rocker switch, letting teams wire load centers at rough-in without breakers present. Integrated LEDs provide persistent trip-condition indication, and Leviton's patented reset lockout prevents reset if ground-fault or arc-fault protection is compromised—adding an extra layer of operational safety. UL listing and RoHS compliance back performance for commercial and residential deployments.

Specify the LB120-AFT for reliable branch-circuit protection in new builds or retrofits where security, monitoring, and surveillance reliability matters. Add to your project bill of materials or order now to protect critical power circuits.
