          Electrical durability




          Electrical durability for AC-3 utilization category - Ue ≤ 440 V.
          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".
