Power Relays, Over 2 Amps

Introduction

A power relay is an electrical component responsible for turning an electrical circuit “on” or “off” based on an external signal or electrical control. Power relays are used in a wide variety of applications and are available in numerous sizes and configurations. One of the most common varieties of power relays is the 4058640000, which is rated to handle current above 2 amps. This article will discuss the application field and working principle of the 4058640000.

Application Field

The 4058640000 power relay is frequently used in power distribution and control systems. It is particularly suitable for use in high-power DC and AC circuits, providing reliable switching signs for currents surpassing 2 amps. In addition, the 4058640000 is often used to regulate the inputs of motors, pumps, and fans. It has an especially wide range of applications in the fields of heating, ventilation, air conditioning (HVAC) systems, audio, and home theater equipment.

Working Principle

The working principle behind the 4058640000 power relay is relatively complex. To understand the device’s operation, it helps to divide the circuit into two distinct sections. The first section is the coil, which is composed of a movable core and an electromagnet. When an electric current is applied to the coil, it creates a magnetic field that causes the core to move. This movement either opens or closes the contact points, depending on the design of the device. The second section is the contacts, which consist of sets of open and closed contacts. The contacts themselves can be closed or opened by the movement of the core. When the contacts are opened, the device is said to be “off.” When the contacts are closed, the device is said to be “on.” The contacts can be set to open at predetermined currents, enabling power relay devices to function according to specific needs. The 4058640000 power relay is a double-pole, double-throw type, which means it has two poles and two throws. The double pole configuration allows the relay to switch two circuits independently of each other, while the double throw configuration allows it to switch a single circuit into two different output positions. With the 4058640000 power relay, the coil usually is rated for 13.5 VDC or 25 VAC, while the contact rating is 16 A at 120/240 VAC or 120 VDC. In addition, the operating temperature range is -40°C to 125°C (-40°F to 257°F). It should be noted that the device is encased in an enclosure that provides it with degree of protection from external elements such as dust and moisture.

Conclusion

The 4058640000 power relay is a versatile and reliable device suitable for controlling large currents in applications such as HVAC, audio, and home theater systems. The device’s efficient working principle allows it to switch two circuits independently, and the high contact rating makes it suitable for a wide range of power distribution applications.
