Terminal Blocks - Panel Mount

Terminal blocks, also known as electrical terminal connectors, are an essential component of any modern wiring system. In their most basic form, they are designed to provide a mechanical and electrical connection between two conductors, usually in form of wires, cables, and other electrical networking components. Panel mount terminal blocks are designed to be mounted onto a panel, and are commonly used for the connection of electrical circuits in power and control systems. They are available in a variety of sizes, styles, and types to suit different types of applications.

Most terminal blocks come in standard sizes such as 5.08mm, 9.14mm, and 10.16mm. A common type of panel mount block is the 3073775, which is a wide terminal with a single and a dual row mounting option. The 3073775 features two 5.08mm pins, with a contact pressure of 1.0 N. The overall dimensions are 5.5 mm x 17.5 mm x 24 mm. This type of terminal block can be used for the connection of current carrying conductors, such as those found in main power circuits. It is suitable for operation at temperatures of up to 85°C.

Terminal blocks are used in a variety of applications, including wiring, control, protection, power transmission, and electrical power distribution. In residential or commercial settings, terminal blocks may be used for panel board connections, wall boxes, or switchboards. In industrial applications, terminal blocks are used for all sorts of wiring applications, including for the connection of control cabinets, machine control systems, power supplies, and other components. One of the main advantages of using terminal blocks is their flexibility, as they allow for the easy connection and disconnection of wire conductors.

Panel mount terminal blocks generally work on the principle of pressure contact. When connected, a spring-loaded contact pushes down on the conductor, resulting in a secure connection. This pressure contact is produced by a separate contact set, which is normally provided with the terminal block. The contact set includes a contact spring and a contact terminal, which are positioned to rest against the contact area of the conductor.

The contact set is usually made of copper or brass, depending on the application, and is generally designed to allow for a high level of current to be carried through the terminal block. This is achieved by a combination of the contact’s shape, the material used, and the design of the contact set itself. The pressure contact created by the contact set ensures a strong connection, particularly in environments depending on good electrical contact. This could include applications such as in hazardous areas, or for power transmission systems.

The main benefit of using terminal blocks is that they provide a reliable, physical connection between two conductors. The actual connection is usually made using screws or terminal screws and an associated cap nut. Some terminal blocks also feature a spring-loaded contact that ensure the connection is maintained mechanically. This type of contact is commonly known as a “push button” contact. In addition to this, they are easy to install, and are flexible and customizable in terms of the type and size of current used.

Panel mount terminal blocks are a versatile and reliable way to provide electrical connection between two conductors. The robust design of these types of blocks make them suitable for use in a wide range of applications, including for power, control, protection, and transmission. The 3073775 is a popular type of terminal block, featuring two 5.08mm pins, a contact pressure of 1.0N, and an overall size of 5.5mm x 17.5mm x 24mm. It is suitable for connection of current carrying conductors, and for temperatures up to 85°C.
