CJX2 Contactor

1. In terms of design, the CJX2 contactor adopts an optimized double-breakpoint direct-acting contact structure and a three-dimensionally arranged magnetic circuit system. The double-breakpoint contact structure makes the arc-extinguishing effect better. The magnetic circuit system has been optimized through simulation, with stable electromagnetic attraction, rapid and accurate action, reducing contact bouncing and wear.

2. The arc-extinguishing system adopts a new type of arc-extinguishing cover and grid structure, which can quickly and effectively extinguish arcs, improving electrical life and breaking capacity.

3. The CJX2 contactor has a low-power design. By improving the electromagnetic system and adopting an energy-saving coil, the coil power consumption is reduced by more than 30% compared with traditional contactors, reducing energy consumption.

● Electrical rating: AC 50/60HZ, 1140V;

● Altitude: ≤2500m. Higher altitude will lead to thin air, poor heat dissipation conditions, reduced air insulation strength, and easy arcing between contacts;

● Ambient temperature: -5°C ~ +40°C;

● Humidity requirements: The relative humidity of the air shall not exceed 50% when the maximum temperature is 40°C; at lower temperatures, higher relative humidity is allowed.

● Installation category: Category III;

● Installation conditions: The inclination between the installation plane and the vertical plane shall not exceed ±5°;

● Current requirements: The rated current level of the contactor shall be reasonably selected according to the rated current of the load to ensure that the rated current of the contactor is greater than the maximum working current of the load.

High Reliability and Long Service Life

The CJX2 contactor uses high-purity silver alloy contact materials, which have excellent conductivity, anti-welding performance and wear resistance. Even with frequent on-off operations, it can stably maintain electrical contact, reducing contact loss. The mechanical life can reach more than 10 million times, and the electrical life can reach more than 1.2 million times. It remains stable and reliable under high-frequency operations and harsh working conditions, reducing equipment failure frequency, maintenance costs and downtime.

High Efficiency and Energy Saving

By optimizing the electromagnetic system of the CJX2 contactor and adopting an energy-saving coil design, the coil power consumption of the CJX2 contactor is reduced by more than 30% compared with traditional contactors.

1. Before installation, please identify the company's trademark;

2. Check whether the rated voltage, current, frequency, auxiliary contacts, etc. in the wiring diagram meet your design requirements;

3. During installation, install according to the specified installation conditions. The A1 symbol on the terminal of the contactor coil should face upward, which conforms to human visual habits;

4. The wiring screws should be tightened. After checking that the wiring is correct, the attraction coil should be energized to open and close several times when the main contacts are not live. It can be put into use only after the action is reliable;

5. If abnormal noise is found during use, it may be that there is dirt on the pole surface of the iron core, please clean the pole surface;

6. During use, each part of the product should be checked regularly. The movable parts are required not to be stuck, the fasteners are not loose, and if any parts are damaged, they should be replaced in time.

Q: What product tests are carried out on the CJX2 series contactors before leaving the factory?

A: The product tests carried out on the CJX2 series contactors before leaving the factory include: appearance and size inspection, installation compatibility test, contact resistance test, insulation resistance and withstand voltage test, short-circuit making and breaking capacity test, etc.

Q: What is the difference between CJX2 series contactors and CJ20 contactors?

A: CJX2: Modular general-purpose contactor, lightweight design, suitable for medium loads and operating frequencies (such as fans, water pumps).

CJ20: Traditional industrial heavy-duty contactor with cast iron base, high temperature resistance and anti-vibration, suitable for extreme scenarios such as crushers and compressors.

Q: What is the contact material of CJX2 series contactors? Is it arc-resistant?

A: Material: Silver tin oxide (AgSnO₂) contacts, which have better arc resistance and anti-welding performance than silver-nickel alloys.

Applicable scenarios: Suitable for motors or resistive loads with frequent start-stop (≤600 times/hour).

Q: What is the protection level of CJX2 series contactors? Can they be used in humid environments?

A: Default protection: IP20 (only prevents finger contact, suitable for dry distribution cabinets).

Humid environment: It is necessary to install an IP55 protection box or select a sealed auxiliary contact module.

Our CJX2 contactor production workshop adopts a modern and intelligent layout design. The entire workshop is divided into multiple functional areas such as raw material storage area, parts processing area, assembly area, testing area and finished product storage area. Each area is connected by an automated logistics transmission system to realize the rapid circulation of raw materials and semi-finished products. The workshop is equipped with a large number of advanced equipment, such as high-speed precision punching machines, automatic winding machines, high-precision injection molding machines, etc. These equipment are uniformly scheduled and monitored through the workshop intelligent management system, which collects production data in real time, optimizes the production process, and ensures efficient and stable production process.
