Control of 3-phase
asynchronous squirrel
cage motors with
breaking while motor
stalled.
The current broken
(Ic) in category AC-4
is equal to 6 times Ie,
where le is the
operational current
of the motor.
Use motor-locked
rotor current (6 times
full-load current) on
horizontal axis for
selection purposes.
