Electrical durability

Electrical durability for AC-3 utilization category
Switching cage motors: starting and switching off running motors. The breaking current Ic for AC-3 is equal to the rated opera-
tional current Ie (Ie = motor full load current). Maximum electrical switching frequency: see "Technical data".
