Product Description
AFR-3s arcflash protection are mainly used to detect arc faults in electrical systems and protect equipment and personnel in
electrical systems from arc faults(flash arc). The arc fault detection 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-3s Arc flash relay is usually used in medium and high-voltage power distribution systems, control cabinets, transformers, generators, motors, and other electrical equipment. The electric arc flash relay adopt the dual-criteria principle of arc light detection and overcurrent detection and have the characteristics of fast protection action and high reliability.
