The NCX1 series AC contactor is mainly used in circuits with AC 50Hz or 60Hz, rated working voltage up to 660V, and rated working current up to 25A. It is used for remote connection and disconnection of circuits, and can be combined with appropriate thermal overload relays to form electromagnetic starters to protect circuits that may operate under overload conditions.
This manual provides the technical specifications, operating conditions, and installation guidelines for the NCX1 series AC contactors. It includes rated voltage and current, compliance standards, and detailed parameter tables for various models such as NCX1‑9, NCX1‑12, NCX1‑17, and NCX1‑25.
The document also describes the control circuit options, auxiliary functions, and mechanical dimensions, helping users select the appropriate contactor and install it correctly in environments up to 2000 m altitude and temperature ranges from –5 °C to +40 °C. This manual is written in Chinese.
