Eaton: Arc Flash Relay

Eaton’s Arc Flash Relay (EAFR) provides reportedly unmatched switchgear protection. This relay reduces arc flash energy by quickly clearing the current feeding the arc. The sensitive light inputs with current permissive detection identify low power phase to ground arc faults. The EAFR works to prevent faults in medium and low-voltage switchgear, and the factory-installed Arc Flash Relay modules and sensors allow for simple integration into electrical assemblies.
