Power Relays, Over 2 Amps: HC4E-L-AC120V Application Field and Working Principle

A power relay is a switch that is activated when a signal or a current reaches a predetermined level or threshold. When this occurs, the relay contacts switch either on or off, completing or interrupting the circuit in the system. The HC4E-L-AC120V power relay is a high-capacity power relay designed for applications that require high current and voltage. This power relay is a lightning-resistant type and offers excellent switching capacity. This article examines the application field and working principle of the HC4E-L-AC120V power relay.

Application Field

The HC4E-L-AC120V power relay is designed for use in environments where high current and voltage is needed. It is suitable for a wide range of applications, including lighting regulation, motor control, and power distribution. It is also suitable for use in lightning-sensitive areas, such as areas prone to sudden changes in temperature, humidity, or lightning strikes. Additionally, the HC4E-L-AC120V power relay is constructed with a solid frame, making it highly durable and suitable for use in harsh environments.

Working Principle

The HC4E-L-AC120V power relay works on the basic principle of an electromechanical relay. When an electrical circuit is connected to the input side of the power relay, the relay coil is energized and magnetized, and the armature is attracted to the electromagnet, activating the contact switching mechanism. This causes the relay to switch on or off. This switching operation is repeated each time the signal or current meets the predetermined level or threshold.

The HC4E-L-AC120V power relay is also equipped with additional protection circuitry. This circuitry helps to protect the relay from any damage due to lightning strikes or other sudden increases in voltage or current. This protection circuitry also helps to reduce the risk of electromagnetic interference or other sources of electrical noise.

The HC4E-L-AC120V power relay is easy to install and use. It has a long lifespan and enables a reliable and efficient operation. It is a reliable and economical solution for applications that require high current and voltage.
