Protective relays and predictive devices

Eaton’s arc flash relay (EAFR) provides unmatched switchgear protection. The relay reduces arc flash energy by quickly clearing the current feeding the arc. 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.

Eaton's arc flash relay

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 set-up provides optional system selectivity, opening the circuit breaker closest to the arc flash.
Flexible module options allow installers to choose between fibre 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 labour 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 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.
