SS-N35 AC contactor with overload

Product Description

In the field of industrial automation, AC contactors with overload function are widely used in the control and protection of motors. They can work stably under high load conditions to ensure the safe and efficient operation of production lines. These contactors can also be used in conjunction with other control devices (such as PLC) to achieve more complex automation control functions and meet the needs of different industrial applications.

In building electrical systems, AC contactors with overload protection also play an important role. They are used to control lighting systems, air conditioning equipment and other power loads, which can effectively prevent circuit overload, reduce fire risks and ensure electricity safety. This safety makes AC contactors widely used in commercial and residential buildings.

AC contactors with overload functions also have important applications in transportation and renewable energy systems. In transportation systems such as railways and subways, they are used to control power supply and ensure the safe operation of equipment. In solar and wind power generation systems, AC contactors are used to protect inverters and other power equipment from damage caused by current fluctuations.

AC contactors with overload function are widely used in many fields, mainly including the following scenarios:

1.Industrial Automation:

In industrial production, AC contactors are often used to control the start and stop of motors, pumps, fans and other equipment. Contactors with overload protection function can effectively monitor the operating status of the motor, prevent equipment damage caused by overload, and ensure the safe and stable operation of the production line.

2.Building electrical system:

In commercial buildings and residences, AC contactors are used to control lighting systems, air conditioning equipment, and other electrical loads. The overload protection function prevents circuit overload, reduces the risk of fire, and ensures safe use of electricity.

3.Transportation:

In railways, subways and other transportation systems, AC contactors with overload function are used to control power supply to ensure the safe operation of trains and related equipment. They can cut off power supply in time when the current is abnormal to protect the safety of equipment and passengers.

4.Renewable Energy Systems:

In solar and wind power generation systems, AC contactors are used to control the operation of inverters and other power equipment. The overload protection function can prevent equipment damage caused by current fluctuations and ensure the stability and reliability of renewable energy systems.

5.Machinery and Equipment:

In various mechanical equipment, AC contactors with overload protection are used to control the start and stop of motors to prevent motor damage caused by excessive load. This is particularly important in the manufacturing, mining and construction industries.
