Jumpers, or terminal blocks, are a type of electrical accessory used in many electronic and electrical applications. They are most often used to bridge two or more electrical circuits in order to complete an electrical path or divert current and voltage to different components. Jumpers are also used in a variety of situations, from facilitating wiring repairs to connecting components between boards.

A jumper\'s function is to bridge two points, effectively creating an electrical connection between them. Jumpers are commonly available in many sizes and shapes, including flexible plastic or rubber meshes, small metal terminals, and large connectors. Many of them have standardized pin configurations that allow for easy and secure connection to the target circuitry.

One of the most common applications for a jumper is in a JN3 application field. JN3 is a type of terminal block that contains three terminals and is most often used to provide electrical connection between three-phase power supplies. This terminal block is placed in between two components that require electrical power to be distributed to one or both of them. It is usually used in conjunction with a circuit breaker or safety disconnect switch to protect the system from any possible electrical overload.

The primary working principle of the JN3 terminal block is to ensure a secure connection between two points. The three terminals are connected using a jumper wire, which is typically insulated or covered in a plastic or rubber casing to protect it from any potential electrical hazards. The insulated material also helps to dissipate heat, as the current passing through the jumper will generate some amount of heat.

The jumper functions as a link between two wires, ensuring an uninterrupted electrical connection. This connection is enhanced by the addition of ceramic insulators, which can reduce the effects of electromagnetic interference and provide a more reliable connection. Additionally, the jumper is usually attached to a fuse to protect the system if an overload occurs.

By utilizing a jumper, two separate components that are connected to a three-phase power supply can be safely and reliably connected without having to run additional wiring. This reduces the need for multiple power outlets and can save time and money in installation and maintenance. In addition, the use of a jumper eliminates the need for large and complex wiring runs, as it requires only a simple and straightforward connection between two points.

JN3 jumpers are an essential electrical accessory for any electronic or electrical application. They are highly versatile and widely used in a variety of situations, from automating repairs and maintenance to making connections between boards. By providing a secure connection between two components, a JN3 jumper can quickly and effectively send power and voltage to many different devices. As such, it is critical to choose the correct jumper for each application in order to ensure a safe and reliable connection.
