MY4-CR AC220/240

Power relays are devices that operate under an electrical signal from a controller to switch a large current. This large current is usually more than 2 amps. The MY4-CR AC220/240 relay is one such device that is suitable for most industrial application fields and meets various needs with different capacities and functions. It is widely used in contactors, motors, lighting systems, water dispensers, heaters and several more. This article will discuss the application field and working principle of the MY4-CR AC220/240.

Application Field

The most common application field of the MY4-CR AC220/240 is in contactors for large motors. The relay is used as an auxiliary power adapter for the coupling connection of low voltage and high voltage equipment. It is also used as main switch for low power components. In lighting systems, the MY4-CR AC220/240 can be used to switch on or off the lights as needed. It can be used as an overload protection device in water dispensers, heaters, and other appliances that draw large amounts of power. The applications also extend to AC motors, such as those found in industrial machinery, as well as for controlling speed and operation of motors.

Working Principle

The main working principle lies in the electrical current switching and controlling capacity of the relay. When the input level of an electrical current activates the relay, it sends a signal to the connected device (motor, light etc.) to turn on or off, depending on the current\'s intensity and type. It works on the principle of two-way current flow, meaning that it can both switch on and switch off the same load. The current switching is usually AC or DC, but AC is the most commonly preferred type.

The MY4-CR AC220/240 is equipped with a control coil and a contact system. When the input energy activates the control coil, it generates a magnetic field. This magnetic field then acts on the contact system, which in turn produces an output that switches on or off the connected device.

The MY4-CR AC220/240 consists of a main, intermediate contact and a main contact strip, which is often referred to as a blade. The main contact connects to the load while the intermediate contact is connected to the control coil. When the current is applied to the intermediate contact, the magnetic field generated by it is used to pull the main contact strip against the intermediate contact, thereby completing the circuit and resulting in a high current being sent through the load.

Conclusion

The MY4-CR AC220/240 is a reliable and powerful relay suitable for various industrial applications. Its robust design and simple working principle makes it suitable for controlling and switching large current. Its applications include contactors, motors, lighting systems, water dispensers, heaters and industrial machinery.
