Eaton arc flash relay

Eaton’s Arc Flash Relay (EAFR) provides 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.

System options on Eaton's arc flash relays

Eaton's arc flash relays provide flexible options allow installers to choose between fiber optic loop cable that is installed in the field and can be labor intensive, or wired point sensors that are factory-installed, reducing labor time and cost as well as streamlining equipment lead times.

The system can measure both light and current to eliminate nuisance operation, and offers an innovative modular design that allows for simple integration into electrical assemblies, ideal for both new and retrofit installations. The system also helps address arc flash safety concerns outlined in National Fire Protection Agency (NFPA) standard 70E, which covers employee workplace electrical safety requirements.

Eaton's Arc Flash Relay

    Arc flash relays core features

    • An innovative module system allows for simple integration into electrical assemblies. 
    • Sensitive light inputs with current permissive detects low power phase to ground arc faults. 
    • The relay’s configurable setup provides optional system selectivity, opening the circuit breaker closest to the arc flash. 
    • Flexible module options allow installers to choose between fiber optic loop cable or wired point sensors. 
    • If the point sensor option is selected, the relay can be factory wired and tested, reducing time and labor costs.

    Help improve your worker safety

    Eaton's arc flash relay is designed to rapidly detect and clear the most difficult forms of arc flash events, reducing the arc energy in low-voltage and medium-voltage electrical assemblies.

    Improve your reliability and efficiency

    As demand for uptime and productivity in oil and gas, utility, manufacturing and infrastructure increases, Eaton's arc flash relay system can help improve the reliability and efficiency of your critical systems and processes.
