■ Integrative structure
■ Built-in LED and keypad afford a precise,digital setting
■ Three-phase monitoring of short-circuit, locked-rotor,overcurrent, undervurrent, phase loss, phase unbalance,overvoltage,undervoltage
■ Powered by the measuring circuit
■ Earth fault (should couple with ZCT)
■ Fault recording
■ RS-485 communication port (optional)
■ 4-20 mA analog output (optional)
■ 2 C/O output contacts, one for trip,one for alert
