ARD

An Automatic Rescue Device (ARD) is a safety system designed to protect electrical installations from prolonged power outages due to faults. When a fault occurs, the ARD automatically disconnects the affected circuit to prevent damage. It then attempts to restore power after a brief waiting period. If the fault persists, the ARD isolates the faulty section to maintain the safety of the overall system. Commonly used in residential and commercial electrical systems, ARDs enhance reliability by automatically restoring power, reducing downtime, and improving safety without the need for manual intervention.
