CJX2 Series AC Contactor: Versatile Power Control Solution

The CJX2 series AC Contactor is an advanced power control device designed for a wide range of electrical applications. This robust contactor is engineered to operate efficiently in circuits with rated voltages up to 660V AC at 50Hz or 60Hz, and can handle rated currents up to 95A. Its primary functions include making and breaking circuits, as well as frequently starting and controlling AC motors.

One of the key advantages of the CJX2 series is its exceptional versatility. When combined with auxiliary components such as contact blocks, timer delays, and machine-interlocking devices, it can be transformed into specialized units like:

Delay contactors
Mechanical interlocking contactors
Star-delta starters

Furthermore, when paired with a thermal relay, the CJX2 series can function as a comprehensive electromagnetic starter, offering enhanced protection and control capabilities.

This high-performance contactor is manufactured in strict compliance with the IEC 60947-4-1 standard, ensuring reliability, safety, and compatibility across various industrial applications.

Whether you’re managing motor controls, lighting systems, or other power distribution needs, the CJX2 series AC Contactor provides a flexible and dependable solution for your electrical control requirements.
