Precautions for Correct Use
Do not connect a contact protection circuit with an inductive load as shown in the diagram
below.
This contact protection circuit is very effective for preventing spark discharge when the circuit is
opened. However, when the contacts are closed, the contacts may be welded due to the cur-
rent charged in the capacitor. DC inductive loads can be more difficult to switch than resistive
loads. If an appropriate contact protection circuit is used, however, DC inductive loads are as
easy to switch as resistive loads.
