Power Relays, Over 2 Amps

The PRD-11DH0-110 is an electrical relay with a contact current rating of up to 2 Amps, a maximum voltage rating of 2400 Volts AC, and a maximum power rating of 5.5 kW. It can be used in a wide variety of applications, from industrial process control to electronic equipment protection. In this article, we will discuss the PRD-11DH0-110\'s application field and its working principle.

APPLICATION FIELD

The PRD-11DH0-110 power relay is employed in many industrial applications. It is particularly suitable for process control with large electrical loads that require multiple control signals, such as hoists, conveyor systems, motor controllers, and machines, among others. It is often used for magnetically or electrically actuated applications. Some common applications of the PRD-11DH0-110 include:

• Motor and Load Tripping/Locking
• Overload Tripping/Locking
• Over voltage Tripping/Locking
• Protection of machines against short circuits
• Protection of lighting circuits
• Thermal protection of transformers, motors and other machinery
• Protection of PV systems

The PRD-11DH0-110 is able to withstand harsh environmental conditions, minimizing environmental impact and providing a high operational reliability.

WORKING PRINCIPLE

The PRD-11DH0-110 employs a single-phase magnetic contactor. It is an electromechanical device that uses an electromagnet to control a mechanical switch. It is activated when a current is passed through the coil of the electromagnet, creating a magnetic field which closes or opens any connected mechanical contacts according to the circuit’s predetermined settings. In other words, when a current is passed through the electromagnet, the contactor is activated and its electrical contacts will either open or close, allowing the power to be transferred to the connected load.The PRD-11DH0-110 is designed to safely open or close electrical circuits. It provides protection against overloads, short circuits and other types of damages. Depending on the models and versions, the rated switching capacity ranges from 1 to 40 Amp (AC) depending on the specific product.

CONCLUSION

The PRD-11DH0-110 is a versatile and reliable electromechanical relay with a contact current rating of up to 2 Amps. It can be used in a wide variety of applications, from process control to overload tripping/locking. Its working principle is fairly easy to understand: it employs an electromagnet to control a mechanical switch, opening or closing any connected mechanical contacts when the current is passed through its coil. The PRD-11DH0-110 provides protection against overloads, short circuits and other types of damages, making it an ideal choice for any application that requires switching capacity ranging from 1 to 40 Amp.
