Leakage Breaker for IoT is designed for 50Hz AC, rated working voltage up to 230V (1P+N, 2P) / 400V (3P+N, 4P), and rated working current of 80A or less. It is mainly used for the control and isolation of low-voltage terminal distribution in residential, industrial, and construction fields, and provides protection against overloads, short circuits, leaks, overvoltage, and undervoltage conditions in low-voltage distribution lines and electrical equipment. It is also suitable for infrequent switching operations. Additionally, it features an open communication interface, supporting 485 serial port, WIFI, 2G, 4G, NB, and other communication methods.
