Series: AFD-01

The AFD-01 is a compact, low-power sensor designed for detecting arc fault currents in 230VAC, 50Hz installations, compliant with IEC 62606. It also provides programmable overvoltage protection via external resistors, meeting EN 50550 standards. Engineered for integration into 18mm-wide circuit breakers, the AFD-01 operates from a 5V regulated DC supply and supports load currents up to 40A. It features a fault signal output that activates a PMR or SCR, along with an LED indicator for visual fault confirmation. The sensor includes a continuous automatic self-test to ensure reliable operation, and a manual test function is available via the Vin/Test pin for additional diagnostics.
