Service life graph
The service life graphs indicate 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.
Cycles x 1000
Switching current (A)
Example
} Inductive load: 2 A
} Utilisation category AC15
} Contact service life: 400 000 cycles
Provided the application to be implemented requires fewer than 400 000 cycles, the PFH
value (see Technical details) can be used in the calculation.
To increase the service life, sufficient spark suppression must be provided on all output
contacts. With capacitive loads, any power surges that occur must be noted. With DC con-
tactors, use flywheel diodes for spark suppression.
