Inductive load with AC voltage
With AC voltage two protection measures are possible:
Example:
EN
Contact protection
measure with voltage-
dependent resistor VDR
Example:
Contact protection
measure with RC element
Capacitive load
With capacitive loads elevated switch-on currents arise. These can be reduced by
series-connecting resistors in the supply line.
Examples: Contact protection measure with current-limiting resistor

5.3 Switch point setting
The switch points have a fixed setting as standard and cannot be adjusted. Thus, an
undesired adjustment of the switch points is excluded.
