Terminal Blocks - Barrier Blocks

433600-09-0 is a type of terminal block known as a barrier block. This type of block has been developed to provide an efficient means of connecting wires in an electrical system. It is designed to break the path of electricity between two points, allowing only certain parts of the electrical circuit to be completely insulated from the rest of the system.

Barrier blocks are typically constructed of polytetrafluoroethylene (PTFE) and range in different sizes from as small as 4 wires up to as many as 150. The versatility of the barrier block allows the user the flexibility to choose the number of connectors in order to accommodate the individual needs of any given project.

Application Field

Barrier blocks are a convenient and cost-efficient choice for a variety of industrial applications that require making and breaking electrical connections. They are often used in complex industrial systems that require the user to make multiple connections at once. Assemblies such as these require precise and complex wiring. The ability to install a barrier block with several connection points enables the user to achieve the desired wiring without complicated setup.

Barrier blocks are also used in control panels, transformer boards, lighting installations, machinery control systems, and any other electrical systems in which multiple junction points are required. Additionally, barrier blocks are used in medical equipment such as cardiac monitors and patient monitors.

Working Principle

Barrier blocks are typically designed with a cleat that opens when pressure is applied but stays closed when the pressure is released. The cleat provides an airtight seal that prevents electrical currents from passing from one side of the barrier block to the other. This prevents electricity from passing through the interconnections, thus keeping them isolated from the rest of the system.

Barrier blocks also have a number of safety features. The cleats can be equipped with micro-switches that cut off power to a particular section of the block in the event of an overload, and they can also be fitted with fuses to reduce the risk of a short circuit.

In addition, many barrier blocks are designed to be attached to other blocks using stainless steel hinges. This allows the user to create a customized wiring system that is efficient and safe. This system can then be easily removed for maintenance or other purposes.

Barrier blocks provide a variety of benefits to any electrical system. They offer a convenient and reliable way to make and break electrical connections without having to install multiple junction boxes. Additionally, they are cost-effective and easy to install and maintain, making them an ideal choice for a wide variety of industrial applications.
