Contactor relays for switching and controlling
Small loads or circuit breakers can be controlled by means of contactor relays. 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.
Contactor relays 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.
