Terminal Blocks - Barrier BlocksTerminal blocks are an essential part of the electrical system in any industrial, commercial, or residential environment. They are wired control systems that allow for the connection of electrical circuits without having to physically manipulate any of the individual wires. Terminal Blocks - Barrier Blocks are a significant component of the terminal block design because they provide electrical separation between several adjacent wires.Terminal blocks start with a metal body, often a solid piece of cut metal, with several small holes or slots for the insertion of the individual wires that need to be connected. The metal body is usually divided into several separate segments, each capable of accommodating multiple wires. The various segments of a terminal block can serve either as a common input point for the wires coming from the source or be connected to any number of individual circuits, depending on the type of circuit involved.Barrier blocks are an extension of the terminal block design and are used to provide additional levels of separation in the wiring system. Barrier blocks are typically used when it is necessary to maintain the electrical integrity of two or more adjacent wires. A barrier block divides sections of wire into distinct segments, each portion of the segment being able to function independently of the others. In a barrier block, each segment is insulated from the adjacent scheme, helping to protect each circuit from short circuits and potential fire hazards. The insulation also helps to ensure that the wires receive the correct amount of voltage, eliminating the possibility of over- or under-voltage from occurring on any of the wiring circuits.Barrier blocks come in a variety of sizes, from small single pole blocks to medium three pole blocks, and up to larger twenty pole blocks. Barrier blocks have two main sections; the terminal block and the barrier. The terminal block serves the same purpose as found in regular terminal blocks; allowing the individual circuit to be connected. The barrier portion of a barrier block is a chamber filled with an electrically insulating material, such as a block of Resin or an Epoxy mixture, that separates the blocks into distinct sections.In most industrial applications, voltage levels are determined before the barrier block is connected, and the barrier block provides a level of insulation that ensures that this predetermined level is not miscalculated. A barrier block, thanks to its insulation, also helps to reduce electrical noise in a system, thus allowing any of the smaller circuits to operate without affecting each other, making them ideal for protecting delicate electronic circuits.Although relatively larger, and often more expensive, than standard terminal blocks, barrier blocks offer a much higher level of electrical suppression protection than a terminal block alone. Not only do they ensure that the predefined voltage level is maintained, but they also protect the wiring from short circuits and protect the delicate electronic circuits from any unexpected signal outages or interference. Additionally, with larger barrier blocks, containing multiple terminals, multiple circuits can connected and run unhindered.Terminal blocks are an important component of any electrical system, but when the need for extra electrical suppression and insulation increases, barrier blocks become the ideal choice for most engineers. With a wide variety of sizes and configurations, barrier blocks offer a level of flexibility and insulation that make these blocks the preferred choice for electrical professionals.
