Small loads or circuit breakers can be controlled by means of contactors. They are suited to control both direct current and alternating current circuits. Using various combinations of contacts (normally closed and normally open) it is possible to switch all kinds of applications. If required, more contacts can be added by installing auxiliary switch blocks.
