Contactors are widely used in almost all the industrial and commercial industries, and the 170360-2 contactor is a multi-purpose contactor with high performance and reliable operation. Its application field and working principle are briefly introduced here

Application Field

The 170360-2 contactor is widely used in power distribution, motor control, heating and ventilating, air conditioning, lighting control, water softening, and other industrial and commercial fields. It is also used in building automation systems, operating large building equipment, and other applications where a low voltage is required.

The contactor is suitable for controlling electric motors; its function is to open and close the circuit connected to an electric motor. It is also used for controlling switches, relays, circuit breakers, and other components of the electric power system.

Working Principle

The contactor consists of two parts: the main contacts and the auxiliary contacts. The main contact is the contact that carries the current, and it is usually made of copper. The auxiliary contacts are the contacts that control the operation of the contactor. They are typically made of silver or other conductive material.

The contactor works by opening and closing the main contacts to form an electric arc. When the contacts are opened, an electric arc is created. This electric arc is then used to heat and vaporize a substrate. When the arc is extinguished, the molten contact material is suctioned back into the contact and the contacts close.

The main contacts are normally closed, meaning that when the contactor is energized, the main contacts will be open. As the current flows, the main contacts will close, forming the electric arc. When the contactor is de-energized, the main contacts will open again, interrupting the flow of current.

The auxiliary contacts act as a safety feature. When the main contacts are opened, the auxiliary contact will open, thus preventing the contactor from being energized again. This prevents any current from flowing through in the event of a fault or over-voltage.

The 170360-2 contactor is a highly versatile and reliable device that is essential in many industrial and commercial applications. Its application field and working principle make it an ideal choice for controlling circuits and devices.
