Terminal Blocks - Accessories - Jumpers

Terminal blocks are components used for electrical connections between wires that need to be suspended or connected to circuit boards. They come in a wide variety of sizes, shapes, connector types, and current capacities, and are often used with safety devices such as fuses, circuit breakers, and relays. While terminal blocks are commonly used in electrical and electronic circuits, accessories such as jumpers are used to ensure secure, reliable connections.

0301479 Application Field and Working Principle

The 0301479 terminal block is a 4-position jumper suitable for both low-voltage (below 1000V) and high-voltage (1000V and above) applications. This terminal block is designed for high-current applications such as panel boards, motor starters, and controllers, while also providing reliable connections in industrial, commercial, and residential settings. It is suitable for automotive and aerospace applications, as well as other harsh environment applications.

The 0301479 jumper is designed with UV and corrosion-resistant nylon, which provides superior durability in extreme temperature and humidity environments. The jumper features a UL 94V-0 flame rating and is UL Listed and CSA Certified for up to 300V/10A. It is rated for up to 600V and 25A, and has an insulation resistance of 5000MΩ.

The terminal block includes two 2.0mm right-angle quick-disconnect crimp stress relief and two 6.3mm flat terminal lugs. These lugs provide secure connections in tight spaces and are designed to provide repeatable results in applications such as motor control and automation. The lugs feature a 2.8mm hole size and are constructed of brass with a nickel-plated finish that provides additional corrosion resistance.

To ensure a reliable connection, the jumper is designed with a universal, field-adjustable screw. Adjusting the screw allows the jumper to be firmly seated against terminal block pins, providing a secure connection between the wires and terminal block. The secure connection ensures minimized electrical resistance, which helps reduce the risk of shorts and arcing.

The 0301479 jumper is also designed with an integral Wire Connector, which utilizes a two-handed, push-to-connect method to quickly and securely connect wires and terminal blocks. The Wire Connector also features a safety lock, which ensures that the connection remains secure. This safety feature is especially important in high-voltage applications.

In addition to providing high-quality, reliable connections, the 0301479 terminal block is designed for easy installation. It features a variety of tools and mounts that make installation convenient and efficient. The jumper is designed with stress relief clips that provide extra stability and help ensure that the connections remain secure. The jumper also features a variety of mounting components that ensure secure installation in a variety of locations.

The 0301479 terminal block is an ideal solution for providing secure, reliable connections in a variety of applications. Its rugged design, wide range of mounting options, and UL and CSA compliance ensure that it will withstand harsh environments and provide excellent performance in even the most demanding applications.
