The CJX9 (3RT) series AC contactors are suitable for any climatic conditions. They are mainly used in AC 50Hz (or 60Hz) circuits with a rated insulation voltage of 690V to 1000V and a rated operational current up to 95A at a rated voltage of 380V under utilization category AC-3, for remote making and breaking of circuits. They can also be combined with a suitable thermal overload relay to form a magnetic starter to protect circuits that may become overloaded.
● The operating mechanism is of direct-acting type with double-break contacts.
● Modular functionality allows accessories to be mounted on all sides except the mounting surface.

● Auxiliary contact modules of SO and above are diversified and interchangeable.
(Note: "SO" may be a typographical variant of "S0", a common frame size designation.)
● Ambient air temperature: –25°C to +60°C;
● Can be installed in any climatic environment;
● Pollution degree: "Pollution degree 3";
● Installation category: "Installation category III";
● In addition to screw mounting, it can also be mounted on 35 mm and 75 mm standard rails;
