A480304, or “barrier block”, is a type of terminal block which is designed and rated to protect up to 600 volts AC. It is typically used in a wide variety of applications including connecting two circuits on the same board, connecting the ground or neutral lines from the input power supply to the circuit board, or even connecting the insulated wires to the circuit board. The barrier block simplifies the connection process, protects the components, and minimizes the risk of accidental shorting or arcing.

A barrier block interfaces with other terminal blocks by having one side attach to the power supply and the other to the circuit board, allowing the power supply and the board to be connected without having to manually twist wires together. The barrier blocks consist of two pieces: one is a terminal block that is installed on the power supply side, and the other is an insulating sleeve that is installed on the circuit board side. The two pieces are then connected together via a terminal connector, which is the actual “barrier”. The terminal connector has holes to accommodate both the power supply and the circuit board wiring.

Once the barrier block is installed, the power supply wires are then inserted into the terminal block, and the board wiring is inserted into the insulating sleeve. The terminal connector is then tightened to complete the connection. This connection allows for yet another barrier of protection between the power supply and the board, reducing the risk of any electrical shock due to accidental contact. As with terminal blocks, barrier blocks can also be used to allow for hot-plug connections between the power supply and the board.

The barrier block uses solid brass construction, which is several times more conductive than copper and has excellent corrosion resistance. The brass construction also allows for higher inrush currents and better reliability than other materials. The barrier blocks are also UL listed, meaning they have been tested to meet UL standards and they are safe to use for high-voltage applications. In addition, they come with crimp terminals which can be installed securely and quickly.

In conclusion, barrier blocks offer an effective way to connect two circuits on a board, or connect the power supply to the board without any of the complications associated with manual connections or individual components. They are easy to use, reliable, and UL listed for safe, high-voltage applications. They are also more reliable than other terminal blocks because of their solid brass construction and their ability to handle high inrush currents.
