Ambient Temperature < 55 °C Maximum number of AC-2 or AC-4 operations: 300 per hour for A 9 . A 40 contactors, 150 per hour for A 50 . A 300 contactors. 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). Millions of operations Breaking current Ic (A) Example: Motor power 59 kW for AC-4 - Ue = 600 V utilization – Electrical durability required = 0.04 million operations. As stated on page 0/0: 59 kW, 600 V corresponds to Ie = 71.1 A. For AC-4: Ic = 6 x Ie = 426.6 A - Select the A 145 contactor at intersection (427 A / 0.04 million operations) on the curves (AC-4 - 440 V < Ue < 690 V).
