Contactor Selection for Utilization Category AC-3
Control of 3-phase
asynchronous squirrel
cage motors with
breaking while
running.
The current broken
(Ic) in category AC-3
is equal to the rated
operational current
(Ie) of the motor.
Use motor full-load
current on horizontal
axis for selection
purposes.

Operational power in kW-50 Hz.
Example: Asynchronous motor with P = 5.5 kW – Ve = 400 V – Ie = 11 A – Ic = Ie = 11 A; or
Use in Category AC-3 (Ve = 660/690 Vac)
NOTE: For Ve = 1000 Vac, use the 660/690 Vac curves without exceeding the corresponding
operational current at the operational power indicated for 1000 Vac.
