Overview
The Leviton LB115-DFT is a 15 A, 1-pole, 120 VAC dual-function branch circuit breaker that combines arc-fault and personnel ground-fault protection in one thermal-magnetic device. It is rated 10 kA and is designed exclusively for Leviton Load Centers with Leviton's all plug-on connection system.
Key Features
-
Dual protection: AFCI and GFCI functions help detect hazardous arcing and ground-fault conditions on the same branch circuit.
-
Reset lockout and diagnostics: Patented reset lockout prevents reset when protective electronics are compromised, while line-side powered LEDs identify trip and fault conditions.
-
All plug-on installation: The breaker connects through the Leviton load-center architecture without a pigtail, supporting rough-in wiring before breakers are installed.
-
Environmental range: Thermal-magnetic construction is specified for operation from -40°F to 158°F (-40°C to 70°C).
