Leviton LB120-AS 20A 1-Pole AFCI Smart Branch Circuit Breaker

Protect critical security and surveillance circuits with the Leviton LB120-AS 20A 1-Pole AFCI Smart Branch Circuit Breaker. Designed for integrators, electricians and facilities managers, this smart circuit breaker combines arc-fault protection with app-based energy monitoring so you can safeguard cameras, NVRs, PoE switches and other monitoring equipment while tracking power usage. The LB120-AS delivers 20A at 120V AC in a compact 1-pole, plug-on package and uses hydraulic magnetic trip technology for consistent performance and fewer nuisance trips across -40°C to 85°C environments.

Installation is faster and more flexible: Leviton's load center design supports rough-in wiring without breakers present, and the plug-on configuration reduces labor on site. Integration with the My Leviton app provides circuit-level visibility and whole-home or site-wide coordination with other Leviton smart devices. Built-in reset lockout and industry certifications (UL, CSA, FCC, RoHS) give added assurance for code-compliant deployments.

Ideal for protecting security, surveillance and monitoring systems, the LB120-AS blends safety, reliability and smart control. Add it to your next project or contact sales for volume pricing and technical support.
