Electrical durability
Electrical durability for AC-2 or AC-4 utilization category
Switching cage motors: starting, reverse operation and step-by-step operation. The breaking current Ic is equal to 2.5 x Ie for
AC-2 and 6 x Ie for AC-4, keeping in mind that Ie is the motor rated operational current (Ie = motor full-load current).
Maximum electrical switching frequency: see "Technical data".
AC-2 or AC-4 - Ue ≤ 440 V - Ambient temperature ≤ 60 °C
