Introduction to Contactors (Electromechanical)

A contactor is an electromechanical device typically used to control power flow in a circuit. It is composed of at least two conducting sets of contacts, operated by electromagnetically-controlled switch arms attached to an actuating coil. It allows for switching on/off a low-voltage current or high voltage current. Contactors are available in a wide range of sizes, designs, and materials to suit the exact requirements of a particular application. They are widely used in a variety of industries for control of electrically operated equipment, such as motors, pumps, fans, and lighting.

CC630SAD200 Application Field and Working Principle

The CC630SAD200 contactor from ABB is a UL-listed, molded case type 3R, 200 amp contactor with a 600 V rating and a 10 hp motor rating. The UL listing comes with the standard version, which includes an electrically operated hermetically sealed contact system. It requires a voltage of 120 - 600 VAC or VDC at a maximum of 2 amps. It can be used in a wide range of applications including motor control, pump control, lighting control, air conditioning, and more.

The CC630SAD200 contactor uses an electromagnetically-controlled switch arm to open and close the electrical contacts. The switch arm is operated by an actuating coil, which is energized when the voltage at the contactor\'s terminals reaches a certain level. This energizing current opens the electrical contacts and allows the electric current to flow. When the voltage drops below a certain level, the actuating coil de-energizes, allowing the switch arm to close the electrical contacts and stop the current flow.

In addition, the CC630SAD200 contactor is equipped with reset and lockout features. When reset is activated, the contactor\'s contacts reset to the "OFF" position. The lockout feature prevents the actuating coil from energizing until all safety conditions have been met. This ensures that the contactor will not inadvertently become energized and cause an electrical hazard.

Conclusion

The CC630SAD200 contactor from ABB is a UL-listed, robust contactor designed for a wide range of industrial applications. It utilizes an electrically operated hermetically sealed contact system, with reset and lockout features for safe operation. The actuating coil is energized when the voltage at its terminals reaches a certain level, allowing the electrical current to flow through the contacts. This allows for reliable remote control of electrical devices, providing flexibility, cost savings, and a safer working environment.
