7. Contact protection measures
7.3. Capacitive load
With capacitive loads elevated switch-on currents arise. These can be
reduced by series-connecting resistors in the supply line.
Examples:

tion measure with
current-limiting
resistor
Contact curve
The hatched area of the contact curve shows the permissible electrical
values for the respective contact.
Accordingly the voltage and/or current to be switched must not exceed
the respective maximum values.
The power to be switched may only lie below the limit curve.
