Function selection
Protect function
Over current Depend on setting time Selectable the inverse/definite
Phase loss Within 3seconds Over 70% of the rate of unbalance
Phase unbalance Within 5seconds Over 50% of the rate of unbalance
Phase reverse Within 0.1seconds Function enable
Stall Within 5seconds Over 180% of the setting current
Lock Within 0.5seconds Setting 200~900% of rated current
Under current Within 3seconds Setting 30~70% of rated current
Ground fault Note) Selectable 0.05~1.0seconds Grounded current setting by dip s/w (100~2500mA)

Note) Lock protection is operated after setting D-time in case of definite time type
