         Electrical durability





         Electrical durability for AC-1 utilization category - Ue ≤ 690 V
         Switching non-inductive or slightly inductive loads. The breaking current Ic for AC-1 is equal to the rated operational current of
         the load.
         Ambient temperature and maximum electrical switching frequency: see "Technical data".
