AFR-3S 3 Channel Arc Flash Protection Relay

Information

Blue Jay AFR-3S is a professional 3 channel arc flash protection relay built with three independent fiber arc sensor inputs. Designed for medium & high voltage distribution cabinets, transformers, generator control panels and motor equipment, this compact DIN-rail unit integrates arc light sensing and overcurrent dual-criterion detection, replacing multiple single-channel protection units to simplify cabinet wiring and cut project costs. This 3-channel arc relay delivers ultra-fast tripping within 10ms to block arc flash explosions, equipment damage and operator injuries. It supports multi-type auxiliary sensors, abundant digital I/Os, built-in fault data logging and Modbus RS485 communication, enabling fast fault location, breaker failure protection and remote intelligent monitoring. Its slim body fits cramped cabinet spaces and works with both visible light and UV ST fiber sensors for stable protection across industrial, new energy and utility power scenarios.
