CJ40 series AC contactors are mainly used for circuit connection and disconnection in AC power systems. They can be combined with thermal relays or electronic protection devices to form motor starters and protect circuits from overload.
This manual describes the CJ40 series AC contactors, which are intended for use in 50 Hz or 60 Hz AC power systems with rated voltages up to 660 V and currents up to 1000 A. It outlines the applicable standards (GB 14048.4, IEC 60947‑4‑1) and typical applications such as motor starters and protective devices.
The document includes normal operating and installation conditions, key technical parameters (rated voltage, current, mechanical life, humidity limits), dimensional data, and wiring diagrams. Tables list the various models (CJ40‑63, CJ40‑80, CJ40‑100, etc.) with their respective ratings. This manual is written in Chinese.
