Terminal Blocks - Barrier Blocks

YK44A1003000G is a member of the Terminal Blocks - Barrier Blocks family of products, specifically intended for applications in which high current and voltage insulation is necessary for a safe and secure connection. This type of Terminal Block is generally used in industrial, automation, energy, power, and process control applications.The YK44A1003000G is designed to allow users to easily and quickly connect different high voltage electrical components. It features two-level insulation—a main barrier assembly (MBA) and an interior barrier assembly (IBA). The MBA is used to separate the high voltage components from the lower voltage components, while the IBA provides further insulation when connecting two different components connected by the two-level insulation block.The YK44A1003000G consists of a high-voltage terminal block sandwiched between two high-voltage insulation blocks. The top of the terminal block is made up of a main brass busbar, while on the lower side, a tin-plated copper busbar provides electrical connection. The two are connected together at the base of the terminal block. This connection is done through two steel compression springs, ensuring that the two bars are securely joined.The YK44A1003000G terminal block is designed to handle extreme high voltages and currents. This is achieved by using specific insulating material and using a separate insulation block in addition to the main barrier assembly. The specific insulation material and the main barrier assembly are key elements in providing effective current and voltage insulation.The working principle of the YK44A1003000G is based on the positive-leading-edge principle. This means that the energy is first delivered to the main brass busbar, and then into the connected components. The energy is then transmitted through the steel compression springs, transferring it to the lower tin-plated copper busbar. The current that flows then goes through the insulation blocks and into the connected components. This ensures that the components are properly insulated and protected at all times.The YK44A1003000G is a reliable and cost-efficient solution for connecting high voltage components. It is easy to install and maintain, and it provides effective voltage and current insulation. This makes it a great choice for applications in which high voltage and current insulation are necessary. With its two insulation levels and the positive-leading-edge principle, the YK44A1003000G terminal block is an excellent solution for a wide variety of applications.
