LCD Display Motor Protection Relay With CT Overload Voltage Current Control Separate

 
GINRI MDB-501Z Voltage Current Phase Monitor Earth Fault Overload Control Motor Protection Relay
 
♦ Features
-- Compact modular size
-- Built-in LCD and keypad afford a precise,digital setting
-- Three-phase monitoring of short-circuit,locked-rotor,overcurrent, undercurrent, phase loss, phase unbalance,overload alarm
-- 1 or 2 phase monitoring of overvoltage,undervoltage
-- Earth fault (should couple with ZCT)
-- RS-485 communication port
-- DC4-20 mA analog output
-- Separated output contacts,two for trip,one for alarm
-- 4 LEDs for status indication
-- Fault recording with last 3 faults
