EOCR-FDE Overview

✔ Built-in MCU (microprocessor controller)

✔ Real-time processing/high accuracy

✔ Overcurrent protection range: 05: 0.5~: 7A 80: 5-80A

✔ Transformer secondary side ratio setting: 1A/5A

✔ Undercurrent protection range: set below overcurrent

✔ Operation time characteristics: Definite time/inverse time

✔ Undercurrent trip output

✔ Undercurrent output and OC output share output,

✔ AL output (07-08) automatically converted to undercurrent (UC) dedicated output contact

✔ Digital display

✔ Three-phase current automatic cycle display: digital ammeter 

    (5 seconds interval for each phase)/1-phase fixed management function according to manual cycle

✔ Trip cause digital display: simple fault, self-diagnosis function

✔ Final trip cause confirmation function: record the last 3 trip causes and trip current confirmation function

✔ Can also be confirmed when power off and re-transmission

✔ Manual (immediate)/auto reset

✔ Fault protection function (FS:ON)

✔ Self-diagnosis function: relay power is on, function during normal operation (selected by setting)

✔ 35mm rail installation, suitable for a variety of environments

✔ Suitable for variable frequency environment system: 20~400Hz

✔ Terminal type and through-type available

• Overload protection, set value (In > overcurrent set value)

• Undercurrent protection, set value (In < undercurrent set value)

• Stall protection during operation, set value (In > 1.5...5 times the overcurrent set value)

• Phase loss protection

• Reverse phase protection

• Stall protection during start-up, set value (In > 2...10 times the overcurrent set value)

• Unbalance protection, (5...50%)

100~240V AC / AC

35mm rail mounting or screw fixing

• 1 NC + 1 NO OL)：one normally closed contact and one normally open contact for overload protection
