Relays and contactors
Solutions for command, switching and load control in industrial and electronic applications.

When control and switching become critical
Recommended choice when reliability, load management and operational continuity are central elements of the system.
- Management of multiple loads and users
- Frequent circuit switching
- Need for isolation and control
- Reduction of plant downtime
When the application
does not require
advanced solutions
Simple applications do not require advanced command and switching systems.
- Limited loads
- Infrequent use
- Low-complexity circuits
- Standard requirements already met
Typical mistake #1:
Incorrect sizing
It can compromise reliability and service life of the component.
Typical mistake #2:
Underestimating switching cycles
Frequent use requires relays and contactors designed for high operational endurance.
Typical mistake #3:
Operating conditions not considered
Temperature, vibration and loads affect performance and operational continuity.

FAQ
Typical questions
Relays are used for command and control of signals or low loads, while contactors are designed to handle high loads and power applications.
A relay that is not correctly sized may wear out quickly or fail to manage the load reliably.
For this reason it is important to evaluate load type, current and number of operating cycles.
A high number of switching operations requires components designed to ensure reliability and long-term service life.
