Power relays are commonly used in kinematic control systems and general signal control systems to control the switching of electrical circuits. They are very important components for controlling electric power, and can be divided into many types according to different parameters. The MK3P-13-DC24 is a special type of power relay, and it is widely used in various applications. This article will discuss its application field and working principle.

Application Field

The MK3P-13-DC24 belongs to the two-pole trip relay type, and its rated working voltage is 24V DC. It has a very wide application field, which includes:

• Automotive components: the MK3P-13-DC24 is frequently used in automotive components such as starter motors, electric fuel pumps, and anti-lock brake systems.
• Appliance manufacturing: the MK3P-13-DC24 is used in the production of a wide range of home appliances, such as refrigerators, air conditioners, washing machines and other domestic electrical appliances.
• Communication systems: the MK3P-13-DC24 is used in various communication systems, such as telephones, intercoms and radio equipment.
• Industrial applications: the MK3P-13-DC24 is also widely used in industrial fields, including conveyers, injection molding machines, automobile assembly lines, and industrial control systems.

Working Principle

The MK3P-13-DC24 power relay is one of the most common and widely used power relay types. It has two poles, one normally open contact and one normally closed contact. When the coil of the relay is energized, the normally open contact closes and the normally closed contact opens. This function is called a “trip relay”, and is used to cut off and prevent power from reaching certain locations. The MK3P-13-DC24 is a “trip-free” power relay, meaning that once the coil is energized, it will remain in the trip position until the power to it is switched off.

The internal structure of the MK3P-13-DC24 contains a set of contact elements, a coil spring, and a frame for holding them in place. When the voltage is normal, the contact elements are in the open position and the coil spring is open. When the voltage is increased, the coil spring contracts, and the two contact elements move together and close the circuit.

When the voltage is decreased, the coil spring expands, and the contact elements open again and the circuit is interrupted. This function is used to control the supply of power to various motors, load switches, and other applications.

Conclusion

The MK3P-13-DC24 is a two-pole trip relay which is widely used in a variety of applications, such as automotive components, home appliances, communication systems and industrial applications. This power relay has two contact elements which move together when the voltage is increased, thereby closing the circuit. When the voltage is decreased, the contact elements move apart to open the circuit again. This type of power relay is very reliable and can be used to control the supply of power to various motors and other devices.
