CJX2-2510 is AC Contactor. An AC contactor is an electrical switching device used for controlling electrical power circuits in alternating current (AC) applications. It is commonly used to control motors, heating elements, lighting, and other electrical loads in various industrial and commercial applications.
The primary purpose of an AC contactor is to make and break electrical connections to turn electrical devices on and off remotely. It consists of a coil, contacts, and an enclosure. When an electrical current is applied to the coil, it creates a magnetic field that pulls the contacts together, allowing current to flow through the main circuit. When the current to the coil is interrupted, the contacts open, breaking the circuit and stopping the flow of electricity.
CJX2 AC Contactor( including LC1-D contactor and LC1-F Contactor),it is suitable for using in the circuit up to the rated voltage 1000V AC 50/60 Hz,and three phase,rated voltage 380V,rated current up to 630A.to switch on and off the circuit at a distance.It is also used as unfrequent start,stop and reversal of AC motor,it is combined into the electromagnetic starter with the thermal relay,combined with the auxiliary contact block, air delayer&machine-interlocking devices,it becomes the delay contactor, mechanical interlocking contactor,star-delta starter,the contactor is produced according to the standard IEC60947-4-1,GB14048.4
