JCZ5-7.2KV series vacuum contactorDetailed product description：

Characteristics of JCZ5-7.2KV series vacuum contactor

• Main circuit
The vacuum switch tube adopts products from well-known domestic manufacturers. Mature technology, reliable quality, and good market reputation.
630A adopts a dual dynamic connection of end face and conductive clip, with low resistance, more reliable, and low temperature rise.
The conductive busbar is aesthetically pleasing and durable, with two options for the upper end: flat or vertical connection, making it convenient for users to use.
Electromagnetic system
The unique built-in large capacity sealed auxiliary switch among similar products greatly improves the reliability and safety of the auxiliary switch.
Optimize the action structure, reduce the starting and holding power of the coil, resulting in lower temperature rise, longer lifespan, and greater reliability.
• Use dynamic armature limit buffer and auxiliary switch head buffer to reduce the impact force of the action and improve the reliability of the action.
3. Action structure
Flexible shaft support, no jamming under force, small axial movement, improved motion performance and consistency.
A reasonable operating mechanism ensures the coaxiality of the axial movement of the vacuum tube's conductive rod. Improved the performance and reliability of the contactor. Make the three-phase synchronization and bounce indicators superior to similar products.
Enhance the contact pressure of the main contact, improve electrical performance and action characteristics. The indicators are superior to similar products.
The mechanical retaining device is self-contained, with a reasonable structure and more reliable use.
4. Easy to use and maintain
The control circuit wiring terminals have functional markings to prevent wiring errors. According to user needs, the wiring terminals can be installed on the two sides or front of the machine for easy wiring. The number of auxiliary contacts can be combined according to usage requirements.
