AC CONTACTOR
9A,12A,18A,25A,32A,40A,50A,65A,80A,95A
The CJX2 (LC1-D) series AC contactors (hereinafter re-ferred to as contactors) are mainly used in power sys-tems with AC 50Hz(or 60Hz), rated working voltage up to 690V, and rated working current up to 95A at a ratedworking voltage of 380V in the AC-3 usage category.They are used for long-distance connection and discon-nection of circuits, and can be combined with appropri-ate thermal overload relays to form electromagneticstarters to protect circuits that may experience operational overload. Contactors are suitable for frequentstarting and control of AC motors.
This series of contactors complies with standards such as GB14048.4-1993 and lEC60947-4
The CJX2 series AC contactor is an automated switch device used for remote control of electrical loads such as AC motors, electric heating equipment, lighting systems, etc. It adopts the principle of electromagnetic attraction to achieve fast circuit switching, with high reliability, long life, low power consumption and other characteristics. It is widely used in industrial automation, building power distribution, mechanical equipment, new energy and other fields.
Working principle:
When an AC contactor is energized, the internal coil generates a magnetic field, causing the moving core and stationary core to attract and close.
This action drives the contact system to connect with the stationary contacts, thereby completing the circuit.
When the coil is de-energized, the magnetic force dissipates, and the return spring pushes the moving core back, separating the contacts and opening the circuit.
