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.
Within its Industrial Controls category, Automation24 offers contactor relays from Siemens and Schneider Electric in various designs with different control voltages. You can also find the right combination of NC and NO contacts to suit every application.
With the auxiliary switch blocks available in the online shop, contactor relays can be flexibly expanded, allowing additional contacts to be added as required.
In addition, compatible accessories for circuit breakers / contactor relays are also available, e.g. in the form of overvoltage limiters, which prevent surges at auxiliary and main contactors.
At Automation24 you will find a large selection of contactor relays to control your main contactors at very attractive prices.
