In the power system, the contactor is a key electrical component, and its performance and reliability are directly related to the stable operation of the entire system. As a spare part widely used in power plants, the contactor CJ12/150-3 provides a reliable electrical control solution for power plant equipment with its excellent electrical performance, high breaking capacity and flexible installation method.

Product Features

1. High breaking capacity

The contactor CJ12/150-3 adopts an advanced electromagnetic system design, and its rated ultimate short-circuit breaking capacity is up to 25kA@415V, which can effectively protect the circuit from damage by short-circuit current. This feature enables it to quickly cut off the circuit in the face of sudden faults, prevent the fault from expanding, and ensure the safety of equipment and personnel.

2. Flexible installation method

Contactor CJ12/150-3 provides a variety of installation options, including fixed front connection and plug-in connection. The fixed front connection method is suitable for scenarios that require stable and long-term operation, while the plug-in connection provides greater flexibility and convenience for quick replacement and maintenance. In addition, the contactor also supports upper and lower line entry without capacity reduction, which provides great convenience for on-site installation and wiring, and can adapt to various complex installation environments

3. High insulation voltage

Its rated insulation voltage is up to 690V, which is much higher than that of general contactors, which enables CJ12/150-3 to work safely and stably in high-voltage environments. This feature is particularly important in the high-voltage power distribution system of power plants, which can effectively prevent electrical faults caused by insufficient insulation and extend the service life of equipment

4. Multiple auxiliary functions

In addition to the basic overload and short-circuit protection functions, CJ12/150-3 also supports a variety of auxiliary functions. For example, it can be equipped with auxiliary contacts and alarm contacts for remote monitoring and fault alarm; it can also be installed with shunt coils and undervoltage coils to achieve remote control and undervoltage protection. These auxiliary functions greatly enhance the intelligence level of the contactor, enabling it to better integrate into modern power monitoring systems.

In the power distribution system of a power plant, Contactor CJ12/150-3 can be used for the incoming and outgoing protection of the main switchboard, sub-switchboard and various electrical equipment. It can effectively distribute electrical energy while protecting the lines and equipment from overload and short circuit. Whether it is high-voltage motors, transformers or other key equipment, CJ12/150-3 can provide reliable protection to ensure the safe operation of the entire distribution system.

Contactor CJ12/150-3 has become a reliable choice for power distribution protection in power plants due to its high breaking capacity, design that meets international standards, flexible installation methods, high insulation voltage and a variety of auxiliary functions. It can not only effectively protect circuits and equipment from overload and short circuit, but also realize intelligent monitoring and control through a variety of auxiliary functions.
