EOCR iSEMZET-WRBT

• Monitors active/reactive power and electric energy (integrated)

• Records fault waves (200ms): Records 3-phase current and 3-phase voltage, and saves the data

• Measures electrical energy through 4~20mA output contacts (+, -)

• Motor insulation status check: Can select from standard insulation resistances of 1MΩ, 5MΩ, and 10MΩ, and diagnose if it is higher or lower than the reference value (diagnosable while motor has stopped running)

• 3-phase current measurement: 0.5~100A with the use of a built-in CT, 100~960A with the use of an external CT

• Allows earth fault protection with the built-in ZCT without having to connect to an external ZCT (0.03~10A)

• The date and time can be checked during a power outage with the Date/Time settings (y/m/d/h/m/s)

• Various protection methods: Definite, Inverse, and Thermal Inverse

• Protects against earth fault current and short-circuit simultaneously (50msec)

• Communication function: MODBUS RS-485

• Records information of the last 3 faults: Fault type, fault current, and fault date/time

• Security settings function (password function)

• Bar Graph display function: Capable of checking the ratio of operating current vs set current

• Restart limit function, operation time setting and display

• Provides software that enables the operator to perform setting and monitoring through a PC
