Example
} Inductive load: 0.2 A
} Utilisation category: AC15
} Contact service life: 2 000 000 cycles
Provided the application to be implemented requires fewer than 2 000 000 cycles, the PFH
value (see Technical details [ 16]) 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.
Permitted operating height
The values stated in the technical details apply to the use of the device in operating heights
up to max. 2000 m above sea level. When used in greater heights, constraints have to be
taken into account:
} Permitted maximum operating height 5000 m
} Reduction of rated insulation voltage and rated impulse withstand voltage for applications
with safe separation:
Maximum operation

4000 m 150 V II 2.5 kV
100 V III 2.5 kV
5000 m 150 V II 2.5 kV
100 V III 2.5 kV
} Reduction of rated insulation voltage and rated impulse withstand voltage for applications

150 V III 2.5 kV
5000 m 250 V II 2.5 kV

} From an operating height of 2000 m the max. permitted ambient temperature is reduced
by 0.5 °C/100 m
