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:

Contact protec-

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.
