EA2-3NU

Signal relays are widely used in electronic and electric systems to control the switch status of an electrical circuit. As the name implies, these relays use low-power electrical signals to control higher power electrical circuits. For example, one may use a small input signal to trigger a powerful electrical device.

The EA2-3NU is a special type of signal relay designed to work within a current of up to 2 amp. It operates up to 7 times faster than a standard relay while still having a low current rating so it is suitable for small signal circuits and applications.

The EA2-3NU is primarily used in industrial control applications to switch and control electrical loads. It is also used in automotive switch control applications. Its low-power input requirement makes it suitable for low voltage and current applications such as HVAC systems, motors and audio amplifiers.

The EA2-3NU has a single coil and is capable of switching up to 3 poles. It has a maximum contact current rating of 2 amp and a maximum coil voltage of 240VAC. It is a 4PDT type relay with the 4th pole used as a common. The EA2-3NU is an ideal choice for applications that require fast switching with minimum power requirements.

The working principle of the EA2-3NU is based on the electromagnetic attraction between the electromagnets and the contacts. When the coil is energized, it creates a magnetic field which attracts the contacts together, thereby creating an electrical circuit. The EA2-3NU is a rugged design and is able to withstand high surge currents.

The EA2-3NU is an ideal choice for applications that require fast switching with minimal power requirements. Its low current rating makes it suitable for small signal circuits and applications. Its rugged design ensures that it can withstand high surge currents. This makes it suitable for a wide variety of applications, from industrial control, automotive switch control and HVAC systems, to audio amplifiers.
