About the AF0500 Arc-Flash Relay

• Plug-and-play installation and a flexible design simplify retrofits and reduce cost. PC configuration is not required, and each input accepts either point- or fiber-optic sensors, saving cost. One AF0500 relay can be set up to trip different zones, eliminating the need to buy separate relays for each zone.
• Unlike competing relays, the unique sensors used with the AF0500 are equipped with a visual indicator called Heartbeat™ that allows workers to verify at a glance that the sensors are properly operating and protection is active.
• The AF0500 relay uses light sensors to detect arcing faults and send a trip signal to the circuit breaker in less than a millisecond. The reduced trip time lowers the incident energy and helps plants comply with OSHA and NEC standards for arc-flash safety.
• It combines all the important criteria needed in an arc-flash relay—fastest reaction time, system health monitoring, ease of installation, scalability, and application flexibility—to protect workers and reduce downtime.
