AC contactor AC contactor
(Quality assurance, price concessions) ◆Overview: Professional supply of Schneider AC contactors.
Low power consumption, long life, safe, reliable, energy-saving, high-quality silver contacts, high resistance to welding and electrical wear.
◆Application scope of AC contactor:
AC contactor is suitable for AC or circuits with voltages up to and current up to, for long-distance connection and segmented circuits
and frequent starting and control AC motors and contactors can also be equipped with building block auxiliary contact groups, air delay heads, mechanical interlocking mechanisms and other accessories to form delay contactors, reversible contactors, star-delta starters, and can be combined with The thermal relay is directly installed to form an electromagnetic starter.
◆Structural features and working principle:
The contactor is mainly composed of electromagnetic system, contact system, arc extinguishing system and other parts.
. Electromagnetic system: The electromagnetic system includes an electromagnetic coil and an iron core, which is an important part of the contactor, relying on it to drive the closing and opening of the contacts.
Contact system: Contact is the execution part of the contactor, including main contact and auxiliary contact. The function of the main contact is to connect and break the main circuit and control larger currents, while the auxiliary contact is in the control circuit to meet the requirements of various control methods.
. Arc extinguishing system: The arc extinguishing device is used to ensure that when the contacts disconnect the circuit, the arc generated is reliably extinguished and reduces arc damage to the contacts.
In order to quickly extinguish the arc during disconnection, the contactor is usually equipped with an arc extinguishing device. Generally, a semi-enclosed longitudinal seam clay arc extinguishing cover is used, and is equipped with a strong magnetic arc blowing circuit.
Other parts: including insulating shell, spring, short-circuit ring, transmission mechanism, etc.
◆The AC contactor has a modular structure and a complete set of functions. Install an air delay head on the top to become a time delay contactor
Add mechanical interlocking functional components to the contactor to form a reversible contactor. After the thermal relay and contactor are assembled, it can become a magnetic starter.
A special current-limiting contact group and current-limiting resistor are installed on the top of the contactor to become a switching capacitor contactor table contactor and air extension head.
The auxiliary contact group can be combined to form a star-delta starter. The device can be installed with auxiliary contacts to form a contactor relay, etc.
◆Normal working conditions and installation conditions:
. The ambient air temperature is: ℃ ~ + ℃. The average value within an hour does not exceed +℃
. Altitude: does not exceed
. Atmospheric conditions: the relative humidity of the air does not exceed % at +℃, and higher relative humidity is possible at lower temperatures. ,
The monthly average minimum temperature of the wettest month shall not exceed +℃, and the monthly average maximum relative humidity of the month shall not exceed %, and condensation on the product due to temperature changes shall be considered.
.Installation Category: Class III Pollution Level: Level
B. Installation Conditions: The inclination between the installation surface and the vertical surface is not greater than
.Shock Vibration: The product should be installed and used without significant shaking, Where there is shock and vibration.
◆Installation is about use and maintenance:
Before installation, the relevant technical data (such as rated voltage, current, operating frequency, etc. should be checked to see if they meet the requirements).
During installation, it should be installed according to the specified conditions. The terminals of the contactor coil should face upwards and conform to human visual habits.
. Contactors with metal mounting base plates must be properly grounded.
. The terminal screws should be tightened. After checking that the wiring is correct, the suction coil should be energized and opened and closed several times when the main contact is not charged. The test action can be reliable before it can be put into use.
If you find abnormal noise during use, it may be that there is dirt on the pole surface of the iron core. Please clean the pole surface.
During use, all components of the product should be checked regularly to ensure that the movable parts are not stuck and the fasteners are not loose. If the parts are damaged, they should be replaced in time
