    EOCR-3DM2/EOCR-FDM2 Protection Project
    Protection project Setting range and conditions Action time
    Overcurrent When the current value on the load exceeds the set current value: 
    Setting range: 0.5 to 60 A (definite time limit) 
         0.5 to 32 A (inverse time limit)
    Time limit: between 0.2 and 30 seconds
    Inverse time limit & overheating inverse time limit: 1~30 Class
    Undercurrent The undercurrent set value cannot exceed or equal to the overcurrent set value when the current value on the load is lower than the set undercurrent 
    value.
    OFF, adjusted between 1 and 10 seconds
    Reverse phase This option can be used when the phase sequence reciprocal of the three-phase current is used 
    .
    Within 0.15 seconds
    Stall This value is set to several times the overcurrent set value. It is only suitable for the start-up process and its setting range can be adjusted. 
    0.5 to 30A: 2 to 8 times 
    to 40A of overcurrent setting value : 2 to 6 times 
    to 60A: 2 to 4 times
    After D-Time time (within 0.5 seconds)
    Stall This value is set to several times the overcurrent set value. It is only suitable for operation and its setting range can be adjusted. 
    0.5 to 50A: 1.5 to 5 times to 60A ofthe overcurrent setting value 
    : 1.5 to 4 times
    Adjust between 0.3 and 5 seconds
    Phase imbalance Condition: Current imbalance ≥ setting imbalance % 
    Setting range: 10 to 50% imbalance
    Adjust between 1 and 10 seconds
    Ground Condition: Ground current setting range when the ground current setting value is exceeded 
    : OFF, 0.05-10A
    Adjust between 0.5 and 5 seconds
