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.

Breaking current Ic (A)
Example:
Breaking current = 9 A.
On the opposite curve at intersection " " 9 A the corresponding value for the electrical durability is approximately 0.6 mil-
lions operating cycles.
