Description

The AFD-01 is a compact, low-power sensor designed for detecting arc fault currents in 230 V ac, 50 Hz installations,

compliant with IEC 62606. It also provides programmable overvoltage protection via external resistors, meeting EN

50550 standards.

Engineered for integration into 18 mm-wide circuit breakers, the AFD-01 operates from a 5 V regulated dc supply and

supports load currents up to 40 A. 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.
