Leviton LB115-AFT 15A 1-Pole AFCI Thermal Magnetic Branch Circuit Breaker

Protect critical equipment and reduce fire exposure with reliable, code-compliant arc-fault protection. The Leviton LB115-AFT 15A 1-pole AFCI thermal magnetic branch circuit breaker combines AFCI detection with thermal-magnetic trip technology to deliver fast, accurate protection for 120V branch circuits feeding security, surveillance, monitoring and IT systems. The plug-on installation supports Leviton load centers and enables wiring at rough-in—speeding project schedules and minimizing panel rework. Integrated LEDs clearly indicate trip condition and fault type and remain illuminated after a trip to simplify diagnostics, while patented reset-lockout prevents resets when protection is compromised. The rocker-style switch reduces actuation force for safer operation in high-density panels. UL-listed and RoHS compliant, this 15A breaker is optimized for powering camera systems, access control, monitoring racks and other low-voltage security loads where uninterrupted protection and fast troubleshooting matter. Specify the LB115-AFT for your next load center or security installation to safeguard circuits and keep surveillance and monitoring equipment online.
