example for
setting of
immediate
overcurrent.
Maximum Current equal to 1.4 x IN of the motor
1) Standard Connection
IN of the switch =170A
IN of the motor =140A
1.4x 140A =196A
196A = 196A = 1.15 x IN of the switch 170 A
IN of the switch
170A
P12 =115% of the IN of the switch =140% of the IN of the
motor
