EN 62606:2013 specifies requirements and tests for Arc Fault Detection Devices (AFDDs) used in low-voltage electrical installations. These devices are designed to detect arc faults, which can occur due to damaged, deteriorated, or improperly installed wiring and equipment, and to mitigate the risk of electrical fires by disconnecting the affected circuit. The standard covers various aspects of AFDDs, including their construction, performance, and testing requirements to ensure reliable and safe operation in detecting and responding to arc faults.
