Electrical durability

Electrical durability for AC-3 utilization category - Ue ≤ 440 V - Ambient temperature ≤ 60 °C
Switching cage motors: starting and switching off running motors. The breaking current Ic for AC-3 is equal to the rated op-
erational current Ie (Ie = motor full load current). Maximum electrical switching frequency: 1200 cycles / hour.
