Fig. 6.1.2.2.-1 Selected safe stall time 30 s
Example:
Start-up current of the motor 6.2 x FLA
Start-up time of the motor 11 s
One hot start allowed
Ambient temperature 20°C
At an ambient temperature of 20°C the internal FLA is 1.09 x FLA of the
motor. Thus, the start-up current of the motor is 6.2/1.09 = 5.69 x the internal
FLA.
