Introduction

The CC18/4SA240 contactors belong to the electromechanical family and are widely used in a lot of different control and automation tasks. These contactors are known for their rugged construction and reliable operation in every environment. The CC18/4SA240 contactors are supplied with high-power AC/DC coils for applications up to 690V with rated current of up to 100A. It is an energy efficient device that is easy to install and maintain.

Application Field

The CC18/4SA240 contactors are ideal for a wide range of applications such as motor control, lighting control, heating and ventilation, industrial process control and a number of other commercial and industrial applications.

It is used for starting and stopping motors and other devices, and for controlling heating, ventilation and air conditioning systems. It is also used in applications such as pumps, fans, pumps, conveyors, hoists, mixers and mixers. loading and welding machines, automated systems, door operators, sign boards, lighting systems and for controlling industrial processes.

Working Principle

The CC18/4SA240 contactors are designed to operate in three different stages. In the first stage when the coil of the contactor is energized, then it magnets around an armature that moves a set of NC (normally closed) contacts, to open circuit. In the second stage, the energized coil pulls down the armature which closes two other sets of contacts. The third stage of operation is when the armature moves up and closes all the contacts.

These contactors are built with a special arrangement of mechanical parts to ensure a reliable and safe operation. It includes a contactor coil, an armature, a set of three contact sets, a restraint assembly, a spring pawl, and a contact switch.

The contactor coil receives voltage from the main power supply that energizes it. The energized coil generates a magnetic field that attracts the armature towards it. As the armature moves upwards it opens the first set of normally closed (NC) contacts. At this point, the spring pawl engages the armature to maintain its position and the two other sets of contacts close completing the circuit.

When the coil is de-energized, the contactor coil loses its magnetic field and spring pawl pulls the armature back down into its original position. This causes all the contacts to return to its normal positions and the circuit is broken.

Advantages

The advantages of using the CC18/4SA240 contactors are numerous. They are reliable and durable having a long service life. They offer high levels of safety for all your applications as they are designed to meet all safety guidelines and standards. Additionally, they are highly energy efficient devices that require low current.

The CC18/4SA240 contactors are easy to install and maintain. They are available in a range of sizes and dimensions to suit any application and are compatible with a variety of other control systems.

Conclusion

The CC18/4SA240 contactors are a reliable and cost-effective solution for a wide variety of motor and situation control applications. They are designed to be highly energy efficient, provide great protection and safety, are easy to install and maintain, and are available in different sizes and configurations. This makes them the perfect choice for many commercial and industrial applications.
