Power relays are a type of electrical switch. While switches are designed to break an electric circuit, relays are designed to open or close a circuit when another circuit is energized or de-energized.

This means that when the switch is turned on or off, the relay will transfer the current from a connected device to turn off or on the device being powered.

The LY3N-AC100/110 is a type of multi-function power relay. It is usually referred to as a 3-pole, 3-NC (normally closed) power relay.

It has a compact size of 12.5mm x 11mm, making it suitable for use in tight spaces within electronic circuits. The contact rating on the relay is 250VAC/12A.

Application Field

Power relays like the LY3N-AC100/110 are used in many different applications. It can be used as a breaker relay to control power to different services, for example, as a switch for mains power. It can also be used to provide remote switching, such as controlling lights from a remote location.

The LY3N-AC100/110 is most commonly used as a motor control relay due to its high switching capacity. The contacts are rated for 250VAC/12A, making it suitable for controlling motors or other heavy loads such as LEDs.

It is also suitable for controlling solenoid valves and other equipment used in automated systems. Its multi-function features make it a versatile option for a range of applications.

Working Principle

The LY3N-AC100/110 works by being supplied with AC mains power. When the voltage across the terminals reaches a certain threshold, this triggers the relay which then switches the current from one circuit to another. The relay is designed such that the contacts are only ever open or closed, allowing a controlled flow of current.

The relay has a range of settings and features that make it suitable for different applications. For instance, it has two different operating modes, timed and non-timed, allowing it to control different devices depending on the functionality required.

The LY3N-AC100/110 is a multi-pole, multi-function power relay that is ideally suited for controlling heavy loads such as motors. It has a compact size and is able to switch power across multiple circuits, making it a versatile and reliable option for a range of applications.
