1. Application

      CJX1-K series AC vacuum contactors (hereinafter referred to as contactors) are mainly suitable to be used in the circuit with AC 50Hz~60Hz, rated working voltage up to 1000V, and rated working current up to 820A, for remote connection and disconnection of circuits. The contactors can be used in combination with appropriate thermal overload relay or electronic protector and other
protective devices to form a vacuum electromagnetic starter, especially suitable for forming an explosion-proof vacuum electromagnetic starter. The contactors are widely applied in mines, smelting, petroleum extraction, storage, chemical industry, military industry, textile, construction and other flammable, explosive or harsh environment.
Compliance standards: IEC 60947-4-1.
