Blue Jay - Model AFR-4 -AFR-4 arc flash detection relay with 4 arc flash sensors
AFR-4 arc flash detection relay is a versatile and independently operating device for bay-based protection. It supports 4-channel arc signal detection and can configure multiple arc tripping modes, ensuring accurate and fast fault isolation. With a fast relay output speed up to 5ms, AFR-4 can minimize or completely eliminate arc flash damage, improving system safety and reliability. It can be used in various arc protection applications in low or medium-voltage power distribution systems. AFR-4 also provides flash warning and dual dual-criterion tripping mechanism (arc detection + current), providing a comprehensive solution for arc flash protection. Integrated RS485/Modbus communication enables seamless remote monitoring and control, which is ideal for modern power systems.Most popular related searches
