Terminal blocks, also referred to as barrier blocks, are essential components of any electrical system. They provide a physical connection between systems, enabling various devices to be connected. Terminal blocks also provide electrical protection, allowing energy to be supplied to one or more components, without risking an overload.

Terminal blocks come in a variety of shapes and sizes, and the general construction of any terminal block, regardless of size and shape, will consist of insulation material such as polycarbonates and nonmagnetic materials, which help protect the wires and their connections from short circuits and other potential hazards. This insulation also helps to ensure that the wire connections remain secure.

The wiring assembly of a terminal block typically consists of a terminal block body, top-hat contacts, spacer blocks, barrier insulation, and accessories. The terminal block body serves as a platform for the contacts, spacer blocks, and other associated components. The top-hat contacts connect the cables to the component, and provide a secure connection that prevents any unwanted disconnection. The spacer blocks prevent the contacts from becoming over-stressed, ensuring a secure connection is made. The barrier insulation is an important safety feature, as it protects the cables from short circuiting and other potential hazards. Finally, the accessories provide additional electrical protection and can include things such as circuit breakers, fuses, and fusible links.

Terminal blocks are used in a vast number of applications across many different industries. Their primary use is in the field of electricity, where they are used both as a power supply controller or to provide a secure electrical connection between two components. They are also used for the connection of multiple cables in networks, wiring systems, and sensors. They can be found in almost any type of electronic component, from simple power supplies to complex microelectronics.

Apart from their primary application in electricity, terminal blocks can also be used in some non-electronic applications. For example, they may be used to join pipes, cables, or hoses. Additionally, they are used in many low-voltage projects, such as telecommunications, where they are used to form the grounding points for different types of conductive components.

The working principle of terminal blocks is quite simple. When the contacts on the top-hat contact and the source of power are connected, an electrical connection is formed and current passes through the contacts. When the contacts are disconnected, the current stops flowing and the connection is broken. This type of connection is suitable for applications in which a secure connection is not required or when the connections need to be periodically reconnected and disconnected.
