Improve worker safety and maximize

equipment uptime with Eaton’s Arc Flash Relay

Eaton’s Arc Flash Relay system helps improve worker safety

and maximize electrical assembly uptime by quickly

clearing arc flash events. Featuring factory-installed Arc

Flash Relay modules and sensors, the system is designed to

rapidly detect and clear even the most difficult forms of arc

flash events in low-voltage (LV) and medium-voltage (MV)

electrical assemblies. Arc faults are the most dangerous

type of fault in LV and MV switchgear. Eaton’s Arc Flash

Relay system reduces the arc energy by clearing the

current feeding the arc.

Features and benefits

• An innovative module system allows for simple integration

into electrical assemblies

• Sensitive light inputs detect low power phase to ground

arc faults

• The relay’s configurable setup offers optional system

selectivity, opening the circuit breaker closest to the arc flash

• Flexible module options allow installers to choose between

fiber optic loop cable and wired point sensors

• If the point sensor option is selected, the relay can be

factory wired and tested, reducing time and labor costs
