1. The built-in release driven by high-performance microprogrammed control unit (MCU) delivers a millisecond-level response and an hyper-precise full electrical parameter protection. 2. Monitor and display in real time comprehensive electrical parameters, including voltage, current, power, power factor, frequency and electric energy (kWh). It is integrated with temperature sensor so as to monitor temperatures of both circuit breaker body and terminal block. 3. It is configured with standard communication interfaces (E.g., Modbus-RTU, Profibus-DP and other interfaces alike), with support for advanced Ethernet protocols (Such as Modbus-TCP/IP and Profinet). It features the incident management and maintenance functions for the data management and firmware upgrade on line.
