Supplementary data
The PFH value depends on the switching frequency and the load on the relay output.
If the values in the service life table are not accessible, the stated PFH value can be used
irrespective of the switching frequency and the load, as the PFH value already considers
the relay's B10d value as well as the failure rates of the other components.
Service life table
The service life table indicates the number of cycles from which failures due to wear must
be expected. The wear is mainly caused by the electrical load; the mechanical load is negli-
gible.
Load type Switching current Number of cycles
DC1 3 A 200,000
DC13 1.5 A 75,000
AC1 3 A 50,000
AC15 1.5 A 50,000
