Power relays, over 2 amps, have a variety of applications, from controlling low-power devices to managing high-voltage electrical services. The HJ4-L-AC100V is a type of power relay with a specific application and working principle.

The HJ4-L-AC100V power relay is a type of heavy-duty relay. It can withstand a maximum continuous current of up to 100A and a maximum power rating of 200W. It is a three-pole, single-throw (ThreePST) relay, meaning it can control three separate high-load circuits with a single switch. The HJ4-L-AC100V also features a contact current rating of 10A and a rated carry current of 11A.

The most common application field of HJ4-L-AC100V power relays is to act as a control switch for high-current electrical appliances. For example, high-current motors, HVAC systems, and water pumps can be wired together with the help of the HJ4-L-AC100V. This type of relay can also be used in industrial control systems as a switch for controlling multiple circuits.

To understand how the HJ4-L-AC100V power relay works, it is important to look at its key features. The relay is constructed from a set of durable and reliable contact switches. These contact switches consist of an electro-magnet, a plunger, and a contact arm. When the relay is energised, the electric current from the power supply flows to the electro-magnet to create a magnetic field. This magnetic field causes the plunger to move, turning the switch on or off depending on the orientation. The contact arm then directs the flow of electric current to the necessary circuits, allowing the user to control multiple circuits with a single switch.

In order to ensure safe and reliable operation, it is important to use a power source that meets the HJ4-L-AC100V\'s operating voltage range (90 - 305v AC). Additionally, proper maintenance of the relay should be done at regular intervals in order to ensure long-term reliability. This may include replacing the contact switches, cleaning the connections, or replacing the entire unit if necessary.

In conclusion, the HJ4-L-AC100V power relay is an ideal choice for controlling multiple high-current electrical appliances and circuits. It has a robust construction, a high maximum current rating, and a long contact life, making it an ideal solution for industrial applications. With proper maintenance, the HJ4-L-AC100V power relay can provide reliable operation for many years to come.
