Power Relays, Over 2 Amps

Relays have been around for centuries. For many years, relays have provided a convenient and effective way to switch and control electrical power. Today, relays are used in a variety of applications, ranging from simple lighting circuits to large industrial equipment. The 3-2158100-5 relay is a versatile, heavy-duty relay designed for use in high-power applications. In this article, we will explore the 3-2158100-5 application field and its working principle.

Application Field

The 3-2158100-5 relay is designed for use in high power applications, including industrial electronics, HVAC systems, and automotive applications. This relay can handle loads up to 30 Amps at 277 VAC, making it suitable for controlling large motors, pumps, and lighting circuits. Due to its heavy-duty construction and high amperage rating, the 3-2158100-5 relay is ideal for applications where reliability and durability are paramount. The relay is designed to withstand extreme temperatures, vibration, shock, and humidity, making it suitable for industrial applications.

Working Principle

The 3-2158100-5 relay is a Form C relay, which means that it contains three separate contacts - normally open (NO), Normally Closed (NC) and Common (COM). When the relay is energized, the NO contact opens and the NC contact closes, allowing power to flow through the relay. When the relay is de-energized, the NC contact opens and the NO contact closes, interrupting power to the load. This type of relay is very reliable and requires very little power to operate.

The relay is typically controlled by a low voltage DC voltage or a low voltage AC voltage. When the input voltage is applied, an electromagnet pulls the armature, which actuates the contacts. This type of control is known as a latching relay because it will remain in the energized or de-energized position until the input voltage is changed. The 3-2158100-5 relay is also equipped with diode protection which helps to prevent electrical damage due to voltage spikes.

The 3-2158100-5 relay is an effective, reliable, and durable switch for high power applications. Due to its robust construction and high amperage rating, it is suitable for controlling large motors, pumps, and lighting circuits. It is also capable of handling high temperatures, vibration, shock, and humidity. This makes it an ideal choice for industrial applications requiring a high level of reliability and durability.
