UE43-3AR3D2 power relay is capable of switching up to 2 Amps of current, offering a reliable and cost-effective solution for various industrial and commercial applications. It is a single-pole, double-throw (SPDT) contact type relay, which has two mechanically operated switch contacts that are normally closed. The UE43-3AR3D2 can be triggered by an AC voltage signal. It\'s quick switching time, low power requirement, and durable construction make it ideal for applications such as motor controlling, switching of resistive and inductive loads, switching and controlling of lights, and temperature and lighting control.

The UE43-3AR3D2 power relay is designed with a suspended contact armature and metal contact surfaces separated by an insulating material. The armature is operated by an electro-mechanical solenoid, which is connected to a control circuit. The relay is powered by the control circuit when it receives an electrical signal, which causes the armature to move and make contact with the metal contact surfaces and complete the circuit. When the signal is removed, the armature spring returns and the contacts open to break the connection.

The UE43-3AR3D2 relay is designed to handle 2 Amps of current or even higher without any issue. It is rated for a maximum current of 250VAC, which is suitable for most applications. The relay is provided with a clear acrylic cover to protect against accidental short circuits. The contact structure of the relay is designed for low contact resistance and long service life, and is constructed from high-grade metal materials that make the relay highly robust and reliable.

The UE43-3AR3D2 power relay can be used in a wide range of applications. These include security systems, lighting control, fan control, and motor control systems, as well as switching and monitoring of AC inductive and resistive loads such as motors, fans, and heaters. In addition, this relay can be used for electrical interlock functions, temperature control, and other similar uses.

The UE43-3AR3D2 power relay can be triggered by either an AC voltage signal or a DC voltage signal. The working principle is simple – a voltage signal is sent to the control circuit, which then triggers the relay. The AC voltage signal is processed by the control circuit and a programmable timer, after which the relay is triggered and the connection between the contacts is completed. In case of a DC voltage signal, the relay is triggered by the voltage, while the programmable timer is reset and the armature is again placed in the normally closed position.

In conclusion, the UE43-3AR3D2 power relay is a reliable and cost-effective single-pole, double-throw contact type relay capable of switching up to 2 Amps of current. It is designed for low contact resistance and long service life, and can be triggered by either an AC or DC voltage signal. The UE43-3AR3D2 is suitable for a wide range of industrial and commercial applications, such as motor controlling, switching and controlling of lights, temperature control, and other similar applications.
