Main Functions and Featuresr
High-performance 32-bit ARM microprocessor is used to carry out signal processing and intelligent control in real time;
LCD Chinese/English display provides friendly HMI and simple operation;
For residual current (leakage)protection,the residual current gear can be set online,with reclosing function;
Monitor and track the residual current of the line in real time,and automatically adjust the gear to ensure the operation rate and reliability of the product;
Long delay,short delay and instantaneous three-stage protection,electronic tripping mode is applied, which is independent of supply voltage;
High breaking capacity could ensure the reliability of short circuit protection for the line;
Overvoltage protection,undervoltage protection,phase loss protection;
Real-time display of residual current,three-phase supply voltage and load current of the line;
Protection functions and parameters can be set and modified online;
Trip types(residual current,locking,overload,undervoltageovervoltage,phase loss)can be identified &displayed,and can be stored,inquired &deleted;
Network type has communication function,which can realize remote communication,telemetry,remote control and remote adjustment;
Pluggable lightning protection module(optional);
Infrared communication function (optional).
