Arc-flash relay

The AF0500 arc-flash relay offers a plug-and-play installation design that is suitable for retrofits in electrical equipment, including switchgear, transformers, substations, motor control centers, load banks, and more. The relay supports four light sensors that allow it to sense an arcing fault, respond in less than a millisecond, and send a trip signal to an upstream breaker to interrupt the fault.  In addition, the product does not require PC configuration and is equipped with a visual indicator called Heartbeat to monitor the health of the sensor.
