Small loads or circuit breakers can be controlled by means of contactor relays. They are suited as control gear for both direct current and alternating current-controlled circuits. Using various combinations of the usually four contacts (normally closed and normally open) it is possible to switch all kinds of applications. If requested, even more poles can be added by installing auxiliary switch blocks.
Contactor relays in control and automation technology
Typical applications are for example:
The reliable screw connection ensures easy wiring of both contactor relays and auxiliary switch blocks.
