Arc flash protection relay AFR-3

currentvoltagepower

AFR-3 Arc flash relays are mainly used to detect arc faults in electrical systems and protect equipment and personnel in electrical systems from arc faults. The arc flash protection relay can detect arcs by monitoring parameters such as current, voltage, and electric power, and quickly disconnect the power supply before an electrical fire occurs, thereby reducing the risk of fire. This AFR-3 Arc flash relay is usually used in medium and high-voltage power distribution systems, control cabinets, transformers, generators, motors, and other electrical equipment. They adopt the dual-criteria principle of arc light detection and overcurrent detection and have the characteristics of fast protection action and high reliability.
