China Air Conditioning Contactor Manufacturer, Supplier, Factory

The working principle of the Air Conditioning Contactor is similar to that of the ordinary AC contactor, which mainly uses the suction force generated by the electromagnet to control the closing and opening of the contacts. When the coil is energized, the electromagnet generates a suction force, which makes the armature move, closing the contacts and completing the circuit; when the coil is disconnected, the suction force disappears, the armature returns to its original position under the action of the spring, the contacts open, and the circuit is broken.

1. Role and Function

Start and Stop Control: The air conditioner contactor can receive control signals and control the starting and stopping of motors, compressors and other equipment in the air conditioning system through its internal electromagnetic mechanism.

Overload Protection: Some air conditioner contactors are also equipped with overload protection. When the load current exceeds the rated value, it can automatically cut off the circuit to protect the equipment from damage.

Remote control: Air conditioning contactors are generally used in conjunction with remote control systems to achieve remote control and automated control of air conditioning systems.

2. Selection and Application

Selection: When selecting an air conditioning contactor, factors such as rated voltage, rated current, working frequency and control requirements of the air conditioning system should be considered. In addition, factors such as the brand, quality and maintenance of the contactor should be considered.

Application: Air conditioning contactors are widely used in air conditioning systems of commercial buildings, residential buildings, industrial plants and other places to control the start, stop, forward and reverse running of air conditioning equipment.

3.Structure and Characteristics

Structural composition: Air conditioning contactors are generally composed of electromagnetic mechanisms, contact systems, arc extinguishing devices and housings. Among them, the electromagnetic mechanism is the key component to generate suction, the contact system is used to control the on/off switching of the circuit, the arc extinguishing device is used to extinguish the arc generated when the contacts are opened, and the outer casing is used to protect the internal components.

Features:

High reliability: The air conditioner contactor is made of high-quality materials and adopts advanced manufacturing technology, ensuring high reliability and durability.

Fast response: The electromagnetic mechanism responds quickly to the closing and opening of the circuit.

Easy installation and maintenance: The air conditioner contactor has a compact structure and is easy to install, disassemble and maintain.
