Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks, also known as terminal boards, are vital components for connecting motor control circuits and other electrical installations. Commonly referred to as headers, plugs and sockets, they make it easy to join sections of circuitry together, providing a secure and stable connection.Terminal boards have been employed in the electrical power sector for over two hundred years. The first models, known as ‘terminal strips’, were used to create power distribution systems prior to the introduction of the modern circuit breakers. They rose in prominence during the 1930s and 1940s with the expansion of the power grid’s adoption of alternating current. Terminal blocks come in all shapes and sizes and their primary purpose is to provide an electrical connection between two or more conducting elements. They are often used to join two interconnecting wires; however, some models are designed specifically to prevent exposed wires from coming into contact with each other. The most popular type of terminal board is the single-pole terminal board. As the name suggests, this type of terminal carries one user-replaceable terminal block. It generally consists of a plastic housing with one or two screws and a raised metal clamping bar. The terminal block itself may be a fixed, insulated type, or one with removable terminals. This type of terminal board is commonly found in motor control panels, and is a popular choice for wiring in various installations due to its affordability and flexibility. At a more advanced level, two- or multi-pole terminal boards are used. These terminal boards are capable of connecting more than one terminal block at once and they come in a variety of sizes, allowing for different wiring configurations. Furthermore, these modules are often designed to accept special connection blocks, such as those used in high-power applications, or terminals specifically designed to handle liquid-cooled wiring. In industrial applications, terminal boards are often used in combination with split-load breakers. These devices are used to segment high-powered electrical systems into smaller sections. By using a split-load configuration, it is possible to limit the power supplied to each section. This helps to prevent the entire system from becoming overloaded in the event of a single fault. In these applications, the breakers are connected to the terminal blocks, allowing the power supply to be divided into multiple parts. Terminal blocks are an integral part of modern electrical systems. Without them, electrical circuitry could not be as versatile as it is today. They provide the necessary connections to ensure a safe and secure flow of electricity, which is why they are often a preferred choice for wiring in industrial settings.
