The AFR-M Busbar Arc Flash Protection Relay is a cost-effective solution designed to safeguard your low-voltage (LV) or medium-voltage (MV) electrical network or system from arc flash incidents. This advanced arc flash relay incorporates a comprehensive three-trip criteria, combining smoke, current, and arc sensing for rapid and reliable detection of busbar arc flashes. By leveraging this integrated arc flash detection, the AFR-M offers exceptional protection capabilities, helping to minimize arc flash damage for personnel and equipment. High-Speed Tripping for arc flash protection The AFR-M arc flash protection relay provide a total trip time of less than 10ms for busbar faults and circuit breaker failure protection. Thus, it can send a trip signal to the circuit breaker as fast as possible. Busbar Arc Flash Protection Busbar arc flash is most likely to occur in busbar room, circuit breaker room, cable room and busbar cabinet, where insulators, conductor connections, switchgear, cable joints and other locations are potential arc flash sources. The AFR-M Arc flash protection relay is designed to monitor the busbar sections within a power system for potential arc fault occurrences. This advanced arc flash relay can monitor up to 48 busbar sections in single-phase, three-phase, or distributed configuration.
