LY4-0-AC120

Power relays are primarily used to switch currents that exceed 2 Amps in various industrial and commercial applications. LY4-0-AC120 is one of the power relays that can provide current switching up to 10 Amps. This article gives an overview of the application field and working principles of the LY4-0-AC120.

Application Field:

LY4-0-AC120 is designed for various commercial and industrial applications that require current switching up to 10 Amps. It is suitable for applications such as HVAC/R, motors and pumps control, lighting control, fans control, process control, motor starters, truck loading, etc. As this power relay can handle up to 10 Amps, it is most suitable for applications that require a higher current switching capability.

Working Principle:

The LY4-0-AC120 is a 4-pole power relay that utilizes an electromagnetic coil to switch an electrical circuit by applying an electrical current through the coil. When the coil is energized, it creates a magnetic field which in turn closes the contacts of the relay. The contacts then provide the current flow to the output circuit, thus switching the desired electrical circuit. Once the coil is de-energized, the magnetic field collapses, thus opening the contacts of the relay and breaking the current flow to the output circuit. In this way, the LY4-0-AC120 functions as a switch for high-current applications.

The LY4-0-AC120 is designed to be connected to either an AC or DC power supply, with an operating voltage range of 120V AC-230V AC or 24 VDC-280VDC. It offers both normally open and normally closed contacts, allowing for versatile applications. It has a maximum switching current of 10 Amps and a minimum switching voltage of 180V, making it suitable for most medium- and high-current applications.

The LY4-0-AC120 has several safety features built in to ensure proper operation and secure operation. It has an IP20 protection rating, ensuring that it is dust protected and resistant to contact with fingers and other objects. It also has a built-in test button that allows for testing of the working condition of the relay. In addition, it has an integrated LED that indicates the status of the relay.

In conclusion, the LY4-0-AC120 is a reliable power relay specifically designed for commercial and industrial applications that require switching of currents up to 10 Amps. It has a wide voltage range and is dust proof and finger safe, making it suitable for many different types of applications. With its versatile switching contacts, built-in test button and LED, the LY4-0-AC120 ensures a secure and reliable operation.
