Contactors for switching and controlling

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.

Contactors in control and automation technology

Typical applications are:

  • Motor and plant control
  • Switching light controls
  • Multiplication of signals

The reliable screw connection ensures easy wiring of both contactor relays and auxiliary switch blocks.

 

Contactors in the Automation24 product range

Automation24 offers Siemens contactors in various versions with different control voltages such as: contactor Siemens 3RH2122-1BB40 and contactor Siemens SIRIUS 3RH21311BB40. They provide a combination of normally closed and normally open contacts for every application. Siemens contactors can be flexibly extended by means of auxiliary switch blocks so that more contacts can be added. The suitable surge suppressors are also available.

At Automation24 you find a large selection of contactors at excellent prices. Select the perfect contactor for your application now!
