LB115AS – LEVITON 1P 20A 120V PUSH IN 10kA ARC FAULT SMART BREAKER

The LB115AS provides Arc Fault Circuit Interrupter (AFCI) protection, which detects dangerous arcing conditions that standard breakers cannot, helping prevent electrical fires. Under the Canadian Electrical Code (CEC), AFCI protection is required for branch circuits supplying outlets in bedrooms, and more recent code editions have expanded requirements to include other living areas. Always verify the applicable edition of the CEC adopted in your province with your local authority having jurisdiction (AHJ).

The smart breaker functionality on the LB115AS enables enhanced circuit monitoring and diagnostics beyond standard AFCI tripping. This can include real-time load monitoring, trip history, and remote diagnostics when paired with a compatible Leviton smart panel system — making it easier to identify and troubleshoot faults without manual investigation at the panel.

The LB115AS is a Leviton LB1-series plug-in breaker and is designed to fit Leviton loadcentres that accept this footprint. It is generally not a drop-in replacement for AFCI breakers from other manufacturers (e.g., Siemens, Square D, Eaton), as breaker-to-panel compatibility is brand- and series-specific. If you're replacing an existing AFCI breaker, send us your panel model number and current breaker details and we'll confirm whether the LB115AS is the right fit.
