Terminal Blocks – Accessories – Jumpers: 475174 Application Field And Working Principle

Terminal blocks are devices used to connect electrical wires or cables to electrical equipment. They are available in varying sizes and styles, depending on how many wires will be used and the type of application. Accessories like terminal block jumpers, also known as bridge bars, are used to connect two or more terminal blocks together and often provide easier installation. The 475174 terminal block jumper, also known as a cross-connection or bridge bar, is commonly used in a variety of industrial and commercial applications.

Applications of the 475174 Terminal Block Jumper

The 475174 terminal block jumper is ideal for connecting transformers to motor starters, variacs, contactors, time-delay relays, and other control devices. It can also be used to wire instrumentation fault circuit interrupters (FCI). The jumper can be used to join two or more paths to create a peer-to-peer connection. It is also commonly used in the construction of staged electrical systems.

475174 Working Principle

The 475174 terminal block jumper has two sides, each with two or three prongs. Each side of the jumper has a twin-tailed wire that can be plugged into the respective terminal block. The jumper\'s electrical conductor is usually made of metal or other conductive material, such as brass, aluminum, or copper. The conductor transmits electricity between the two terminal blocks it is connected to, completing the circuit.

When the 475174 terminal block jumper is connected, one side of the circuit is typically powered by a battery or wiring from a power panel, while the other side of the circuit is typically connected to either a load or outlet. The jumper conducts the electricity between the two terminals, allowing it to flow through the connected wires or cables. To protect the connected equipment from power surges, short circuits, or other electrical hazards, the jumper is usually rated to handle certain maximum amounts of current and voltage. This can be identified by the voltage and amperage settings printed on the side of the jumper.

Conclusion

The 475174 terminal block jumper is an essential component used in electrical wiring systems and construction. Its working principle is based on creating a two-way current flow between two terminal blocks, helping to ensure a safe and reliable electrical connection. The jumper is suitable for industrial and commercial applications that require a fast and easy way to connect electrical equipment. Whether it is connecting transformers to motor starters, variacs, contactors, or other control devices, the 475174 is sure to fit the bill.
