EOCR 3EZ-WRAZ7A

• Built-in MCU (Micro Controller Unit)

• Real time processing/higher precision

• Over current protection range: 0.5~60A, wide range protection (1~960A with an external CT)

• Under current protection range : The set over current or less

• Earth fault current protection range: Earth fault protection via zero current detection / 0.02~3A (Definite operation)

• Over current protection operation time characteristic: Definite - 0.5~60A (external CT combination for over 60A) Inverse - 0.5~10A (external CT combination for over 10A)

• Earth fault protection operation time characteristics : Definite : 0.05~10 sec

• Digital Display - Auto circulation display on 3-phase current and earth fault current : Digital Ammeter (every 5 sec for each phase) - Allows fixed management on single-phase or earth fault current via manual circulation - Trip cause digital display : Easy Troubleshooting

• Last trip cause check function: Can check the last 3 trip causes and current at the occurrence of each trip. Available even during the recovery of electricity after a power outage.

• The actual current % on current change and current set value can be easily identified via a Bar Graph (FEZ type)

• Manual (instant)/electrical (remote) reset

• Also works well on frequency converter systems (e.g., inverter): Frequency response range 20~400Hz

• Fail Safe function (FS:ON): Self-diagnosis function - when power is supplied to the relay, the relay is normally energized

• Applicable in various installation environments, with both terminal and hole types
