Precise measurement and control
Real-time monitoring of multi-side electrical quantities such as ULN/ULL/I/P123/P∑/Q123/Q∑/S123/S∑ /PF123/PF∑ /F/EP+/EP-/EQ+/EQ-/3I0 with high measurement accuracy

Comprehensive protection
Provides differential quick-break, ratio differential, differential current over-limit, overcurrent 1/2/3 sections, zero-sequence overcurrent, overvoltage, low voltage, system power loss, too high frequency, too low frequency, PT disconnection, CT disconnection and other protections, and integrates non-electricity protection interfaces

Intelligent communication
Built-in communication management machine and fiber optic ring network switch support multiple protocol conversions and can flexibly access various smart devices and build a reliable communication network

Record function
Detailed records of protection actions, event alarms, remote signaling events, operation logs, self-test events and fault recording data facilitate fault analysis and system diagnosis.
