Separate Structure Electronic Overload Relay Earth Fault 4-20mA Analog Output
Advantage
1) Integrative structure or Separate structure
2) Built-in LED and keypad afford a precise,digital setting
3) Three-phase monitoring of short-circuit, locked-rotor,overcurrent, undervurrent, phase loss, phase unbalance,overvoltage,undervoltage
4) Earth fault (should couple with ZCT)
5) Fault recording
6) RS-485 communication port (optional)
7) 4-20 mA analog output (optional) unbalance,overvoltage,undervoltage
8) 2 C/O output contacts, one for trip,one for alert
