CJX2-09 mini contactor

Scope of application

CJX2 AC contactor is a commonly used electrical equipment for factory power distribution control. It is mainly used for communication channels with voltages ranging from 50-60 Hz to 690 V and currents within the specified (optional) range. It is mainly used for long-distance connection and disconnection of circuits in AC circuits, and is suitable for frequent starting and control of AC motors, forward and reverse rotation, etc. It can also be combined with appropriate thermal overload relays to form an electromagnetic starter for protecting circuits that may experience operational overload.

In the circuit with rated working voltage of 380V and rated current of 620A under AC-3 service category, it is used for remote connection and breaking of circuits, and can form an electromagnetic starter with appropriate thermal overload relay to protect the circuit that may have operation overload. The contactor is suitable for frequent starting and controlling AC motor.

The product complies with GB14048 4. Lec60947-4-1 standard.
