Power relays, over 2 amps, are electrical switches which are designed to switch large amounts of electrical current. They are often used in industrial settings to control large motors, cut off current during short circuits or for overload protection. The J7KNA-09-01R 110 relay is a great example of a power relay that has a wide variety of applications.

The J7KNA-09-01R 110 is a general purpose unit that has a coil rating of 110 VAC at 50/60 Hz. It is rated for a maximum switching current of 28 amps and a maximum switching voltage of 240 VAC. It features 4 poles, a 2 form C contact arrangement, and three screw terminals for a convenient installation. It also has an LED indicator to show when the contacts are on or off.

The most common application for this type of relay is overload protection. An overload occurs when too much current flows through a circuit, usually due to a short circuit or just too much current draw from the system. To protect the circuit, a power relay can be used to shut off the current flow when the load gets too high. This prevents the circuit from being damaged and keeps the system safe.

The J7KNA-09-01R 110 relay can also be used to control large motors. By connecting the relay to power source and the motor, the relay can be used to turn the motor on and off as well as change the speed of the motor. This is helpful in applications such as industrial machinery, where precise control over the motor is required. The relay can also be used for time delay operations since it can be set to open and close the contacts at a specific time.

The working principle of this power relay is also quite simple. It consists of a coil which is energized when the relay is triggered. This, in turn, moves a metal armature which then closes or opens the contacts, thus allowing or preventing the flow of current. The current that is allowed to flow through is then regulated by the size of the contacts and the type of load that is connected.

In summary, the J7KNA-09-01R 110 relay is a great choice for those who need to control large amounts of voltage and current. It is ideal for overload protection and controlling large motors, as well as for time delay operations. It is a durable and reliable product that has a wide variety of applications and a simple working principle.
