Operating Manual PNOZ s3

21395-EN-10

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.

Example

} Inductive load: 0,2 A

} Utilisation category: AC15

} Contact service life: 2,000,000 cycles

Provided the application requires fewer than 2,000,000 cycles, the PFH value (see techni-

cal 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 contac-

tors, use freewheel diodes for spark suppression.
