Electrical Durability for AC-3 Utilization Category 03
Switching cage motors: starting and switching off running motors. The breaking current Ic for AC-3 is equal to
the rated operational current Ie (Ie = motor full load current). Ambient temperature and maximum electrical
switching frequency: see "Technical Data".
