VR111B080CE-6C

VR111B080CE-6C is an adjustable three-phase AC contactor designed to handle small motor starting applications. This contactor is used in a variety of medium voltage applications and can be used as a stop switch in a pump or fan motor control circuit. It has a wide range of voltages and current ratings and can be used in various applications where either a three-phase motor starter or an individual motor starter is needed.

Application Field

The VR111B080CE-6C is a type of adjustable AC contactors, commonly used in various industrial and commercial applications. It is used mainly in low- and medium-voltage power distribution to control the motor start up and shutdown of motors, pumps, and other electrical loads. This contactor works by switching the current flow between two load reactors: the motor and a series reactor. The motor is connected in series with a generator for optimal power conversion, while the reactor balances the current and prevents overloads on the motor and other components.

The VR111B080CE-6C is mainly used in motor control applications where its electric performance makes it an ideal choice for medium and high power applications. It can be placed between the power supply coming from a service switch or main power distribution point and the motor or electric load. It is often used in applications such as pump, fan, and compressor controllers and motor controllers of any kind.

Working Principle

The VR111B080CE-6C is a type of contactor designed for motor control applications. Its main purpose is to control the start and stop of the motor and to provide overload protection. To do this, the contactor is designed with a set of contact points that act as a switch, allowing current to flow through the motor when it is on and stopping current flow when the motor needs to be switched off. It also has overloading protection that will shut off the motor if it is experiencing an overload.

The contactor is constructed with two poles and usually fitted with a protective coat of insulation. When the poles are connected, current will flow through the motor and its associated load. This connection is secure and allows for a smooth and quick connection and disconnection of power. When the contactor is open, it will stop the flow of electricity and disconnect the power.

The contactor is also usually fitted with an additional switching device that will help prevent excessive current and heat buildup. This auxiliary contact is also used to provide status and safety feedback, ensuring that the motor is running correctly. In some applications, the contactor can also be fitted with an emergency override switch that helps to control the motor in the event of an overload or other emergency situation.

Conclusion

The VR111B080CE-6C is a highly efficient contactor designed for motor control applications. Its adjustable range of voltages and current ratings makes it suitable for different power systems and applications. It can be connected to a variety of mediumvoltage power sources and is often used in motor control applications like pumps, fans, and compressors controllers. Its built-in over-current protection makes it a dependable choice for motor control and its auxiliary contact provides status feedback, helping to ensure the motor is running correctly at all times.
