Contactor, also known as contactor switch, is one of the most important components in the electronic circuit. It is an electromagnetic switch used to control large electrical loads such as motors, lights, heaters, etc. Its contact forms the most basic connection in the power grid.

CGMS-12A-230-01 is a typical three-phase AC contactor. With compact size and high quality, including sophisticated mechanisms and copper components, it is well-received among customers. The contactor is designed for applications in the fields of construction, HVAC, agricultural machinery, machine tools, water pumps, air compressors, and other motor-driven systems.

In general, the CGMS-12A-230-01 contactor consists of three parts: the stationary part, the movable part, and the thermal device. The stationary part, usually called the base, is the stationary support for housing the rest of the contactor components. The stationary part of the CGMS-12A-230-01 contactor also provides the contacts for the control circuit. The movable part, usually referred to as the armature, is an armature suspended on a building containing a coil that is connected to the power line. Finally, the thermal device is a protection unit which enables the contactor to withstand the heat generated during its operation.

The principle of the contactor is essentially the same as a traditional electrical switch. When a DC voltage is applied to the coil of the contactor, it creates an electromagnet and changes the polarity of the magnetic field in the air gap between the armature and the pole pieces. As a result, the armature of the contactor is pulled towards the pole piece and two sets of contact points make contact with each other. This establishes a reliable electrical circuit and current is allowed to flow. When the voltage is removed from the coil, the electromagnetic field collapses, the armature moves back from the pole pieces and disconnects the circuit.

In addition to the contactor\'s regular functions, other functions can be added if required, such as lamp failure, voltage absence, control, overload, short circuit and so on. These protectors can be assembled in the contactor base.

In conclusion, the CGMS-12A-230-01 contactor is an important component in the electronic circuit. It has a wide range of applications in many different fields and can be used to effectively control large electrical loads. Furthermore, it is durable and reliable, and provides additional safety and protection functions if required.
