Example
} Inductive load: 0.2 A
} Utilisation category: AC15
} Contact service life: 1 000 000 cycles
Provided the application to be implemented requires fewer than 1 000 000 cycles, the PFH
value (see Technical details [ 22]) can be used in the calculation.
To increase the service life, sufficient spark suppression must be provided on all relay con-
tacts. With capacitive loads, any power surges that occur must be noted. With DC contact-
ors, use flywheel diodes for spark suppression.
