Contactors (Electromechanical)

Contactors are devices that provide complete control and protection of circuits and motors, and are widely used in industrial and commercial applications. The electromechanical contactor CC40SA220 is designed for switching applications in heavier loads and rated current up to 220A. In this article, we will discuss the applications and working principles of this contactor.

Application Field

The CC40SA220 Contactors can be used in a broad range of applications, including controlling large motors, such as those used in the paper-making machines, pump-control systems, and conveyor-control systems. Additionally, it can be used to switch the lighting, heating, and air-conditioning installations. They are also suitable for other high switching duties such as fusing, transformer control, and rectification. This contactor is a reliable and cost effective solution for all these industries.

Working Principle

The CC40SA220 consists of an armature, an electromagnet, and spring-return contacts. The electromagnet is activated when a control voltage is applied. When the electromagnet is energised, it attracts the armature and the armature moves to compress the spring-return contact, thus closing the circuit. The contacts are maintained in the closed position for as long as the voltage is applied. When the voltage is switched off, the spring-return contact opens, breaking the circuit. The contactor has an integrated overload release mechanism which automatically trips the contactor when the current overloads, thus providing protection for the electric circuit. The mechanism is made up of a copper disk and a bimetallic disc which is heated up by the current. When the current exceeds the maximum rated current, the bimetallic disc bends and the copper disk is pulled back and releases the armature, thus opening the circuit and preventing further overload.

Conclusion

In conclusion, the CC40SA220 electromechanical contactor provides reliable and cost-effective solutions for a variety of industries. It is used for switching large loads and rated current up to 220A. The contactor is also equipped with an integrated overload release mechanism that provides protection for the circuit. With these features, the CC40SA220 contactor is a reliable solution for all these industrial applications.
