1.5P 25A Air AC Conditioning Contactor

Principle of Operation

When the coil of the 1.5P 25A Air AC Conditioning Contactor is energized, the iron core becomes magnetic and attracts the contact system to close, thus connecting the electrical load to the power source. When the coil is de-energized, the iron core loses its magnetism and the contact system is separated by a spring, thus disconnecting the load from the power source. In this way, the contactor allows remote control of the electrical load.

Definite Purpose Contactor Application:

• CJX9 (Or STA) Series Air Condition AC Contactor is mainly applicable to a line of AC 50Hz or 60Hz, rated insulation voltage is 240V and rated working current up to 60A, used to close or switch off the line

• Air conditioner contactors are definite purpose AC contactor are designed for use in refrigeration, air conditioning, and electric heating systens.

• Power connections can be made with either screw terminals with quick connects or lug terminals with  quick connects

• They comply with IEC60947-4-1

Structure and Features

Structure:

Electromagnetic system: including coil, core and other components, used to generate magnetic flux to drive the opening and closing of the contact system.

Contact system: including main contact and auxiliary contact, the main contact is used to carry high current, and the auxiliary contact is used to realize the transmission and feedback of control signal.

Arc extinguishing device: Used to extinguish the arc generated when the contact is disconnected to protect the contact from damage.

Shell: used to protect the internal components from the external environment, while providing heat dissipation.

Features:

With a well-defined purpose and specific design for specific power systems and load types.

The contact system is manufactured from high quality materials with good electrical conductivity and wear resistance.

The electromagnetic system has sufficient suction force to reliably engage and release the contacts.

The arc extinguishing device can effectively extinguish the arc and protect the contacts from damage.

The shell is reasonably designed with sufficient strength and heat dissipation performance.
