       Electrical durability





       Electrical durability for AC-1 utilization category - Ue ≤ 690 V
       Note: AC-1 maximum current is selected according to ambient temperature. Please see technical data.
       Switching non-inductive or slightly inductive loads. The breaking current Ic for AC-1 is equal to the rated operational current of
       the load. Maximum electrical switching frequency: 600 cycles / hour.

       Example:
       Breaking current = 9 A.
       On the opposite curve at intersection " " 9 A the corresponding value for the electrical durability is approximately 0.6 millions
       operating cycles.
