RS485 Control Monitoring Circuit Breaker-WRSM1L-2P

WDYK RS485 Control Monitoring Circuit Breaker,This product is an intelligent low-voltage distribution component that integrates distribution protection, precise electricity metering, residual current monitoring, and remote data exchange. It integrates high-precision current/voltage transformers, professional energy metering chips, leakage detection zero sequence transformers, and RS485 communication modules internally. It not only has the overload and short-circuit instantaneous protection functions of traditional circuit breakers, but also can monitor the residual current (leakage value) of the line in real time. When the leakage current exceeds the preset threshold (such as 30mA, 100mA, and other optional gears), the circuit can be quickly disconnected to ensure personal and equipment electrical safety. At the same time, the metering module can accurately collect and calculate power consumption data such as active power, reactive power, total energy, and time-sharing energy of the line. It follows standard communication protocols such as Modbus RTU through the RS485 interface to achieve network connection with distribution monitoring hosts, smart meter concentrators, and other devices. It supports remote reading of power consumption data, modification of protection parameters, and querying of leakage fault records.
