Setting range: 0.5~60A (Definite time limit - Def)
0.5~32A (inverse time limit - Inv, overheating inverse time limit - th) Time limit: 0.2~30 seconds optional inverse time limit and overheating inverse time limit: 1~30 level Undercurrent The load operating current (ln) is lower than the set overcurrent value (uc), ie ln ≤ uc
Undercurrent value setting cannot exceed or equal to overcurrent setting value OFF, adjustable from 1 to 10 seconds Stall This value is set to a multiple of the overcurrent setting value. It is suitable for the setting range during startup: 0.5~30A 2~8 times of the overcurrent setting value is more than 2~6 times of the 40A overcurrent setting value until 60A 2 to 4 times the current setting value 0.5 seconds after D-Time Stall This value is set to a multiple of the overcurrent set value. It is suitable for the setting range during operation: 1.5~5 times of 0.5~50A overcurrent setting value up to 1.5~4 times of 60A overcurrent setting value. Adjustable from 0.2 to 5 seconds Missing phase The maximum phase imbalance ratio of the three-phase current exceeds 85% (OFF/ON) OFF, adjustable from 0.5 to 5 seconds Reverse phase The phase sequence of the three-phase current is not reciprocal (OFF/ON) OFF, within 0.15 seconds Current imbalance Current imbalance rate = (maximum phase current - minimum phase current) / maximum phase current × 100%
Current imbalance rate ≥ set current imbalance rate setting range: 10~50% Adjustable from 1 to 10 seconds Ground Exceeding the setting ground current value setting range: OFF, 0.03~10A Adjustable from 0.05 to 10 seconds EOCR-3MZ2/FMZ2 technical parameters Current range Overcurrent Definite time: 0.5-60A, greater than 60A using external CT
