CJX2-D170 High Ampere AC Contactor 170A
Ac contactors – Definition & Types
An AC contactor functions as an electromechanical control device designed to establish or interrupt electrical connectivity between power sources and high-capacity loads. Equipped with integrated voltage transient suppression, these devices provide reliable switching operations in power distribution systems. Their primary applications encompass electrical apparatus control and power network management, particularly for operating industrial-scale loads such as motor drives, thermal regulation systems, and illumination control circuits.
As a standardized switching solution, AC contactors serve as critical interface components between control circuits and power equipment, enabling remote current regulation through low-power signal commands. Distinct from circuit protection devices, contactors maintain closed contacts under normal operation until receiving an open command or fault-induced automatic disengagement, ensuring continuous current conduction during equipment service cycles.

Technical Specification
The AC contactor CJX2-D170 is an electrical appliance used to control AC power, which has one or more main contacts and one or more auxiliary contacts. It is usually composed of an electromagnet, armature, and conductive mechanism to generate current and transmit it to the circuit. It has the following advantages:
1. Strong control ability: This contactor can achieve on/off control and switching functions for the circuit, and can flexibly control according to different needs.
2. Efficient and energy-saving: The electromagnet of the AC contactor is powered by a DC power supply, which has high efficiency and can reduce energy consumption and waste. At the same time, when used in conjunction with the motor, the contactor can effectively reduce the starting current and operating loss rate of the motor.
3. High reliability: AC contactors are usually made of high-quality materials, with a compact and durable structure, long service life, and low failure rate; In addition, its internal design has comprehensive protection and overload protection measures, improving the reliability and safety of the equipment.
4. Multiple protection mechanisms: In addition to basic disconnection and protection functions, AC contactors are also equipped with various safety protection devices, such as fuses, thermal relays, etc., which can effectively prevent dangerous accidents or damage to equipment in abnormal situations.
5. Economical and practical: Compared to other types of switching appliances, such as solenoid valves or relays, AC contactors are relatively inexpensive, easy to operate, and easy to maintain and manage. Therefore, AC contactors are widely used as one of the core components of electrical control in various industrial and civil occasions.
