Maximum Switching Power of Output Contacts
The useful life time is limited by the maximum number of switching cycles under load
conditions. The maximum number of switching cycles is depending on the electrical load
and may be higher when reduced currents and voltages are applied.
You can see the relationship between the maximum switching power and the load conditions
in the figures below.
