Terminal Blocks - Panel Mount

Terminal blocks, also known as terminal strips, are devices used to secure and terminate wires and cables. They are used widely in industrial settings due to their ability to handle the heavier gauge wiring sizes associated with such applications. Panel mount terminal blocks are a subset specifically designed to be mounted onto a panel. This article looks at the application field and working principle of this type of terminal block.

Application Field

Panel mount terminal blocks allow for a secure and reliable connection between rigging cables and field wiring. This type of connection is commonly used in electrical control systems. Applications include HVAC systems, industrial process control, and instrumentation and automation systems. Panel mount terminal blocks are also commonly used to connect circuit boards and other high-powered components to a central power source, such as an enclosure. They are also used to connect auxiliary equipment or external devices to the main power supply. Due to the robustness and reliability of this type of connection, the terminal blocks are widely used in many industries, including aerospace, healthcare, and telecommunications.

Working Principle

Panel mount terminal blocks operate on the principle of a clamping device. When a conducting wire is inserted into the clamp, it is tightly secured by the terminal blocks’ metal clamping arm. The wire is held in place via the tension generated when the clamping arm is tightened. The clamping arm also acts to maintain electrical contact between the connected wires and ensures that the connection is completely isolated from the surrounding environment. It is also able to secure wires of various gauges, allowing for versatile use. The wire is then insulated using a variety of methods, such as heat-shrink or rubber covering. This insulation helps to reduce the risk of electrical shock and keeps the wiring free from dirt and other contaminants.

Benefits

Panel mount terminal blocks offer numerous benefits that make them a popular choice for industrial applications. Firstly, they are extremely easy to assemble and install. As the wires are held in place through the tension generated by the clamping arm, there is no need for adhesives or other fixings to ensure a secure connection. Secondly, they offer superior insulation and protection from potential electrical hazards. Finally, they are suitable for a wide range of applications, and are compatible with both standard conductor sizes and more customised wiring. This makes them an ideal choice for projects where a more significant degree of customisation is required.

Conclusion

Panel mount terminal blocks are a versatile and reliable solution for securely connecting circuit wiring and cables. They are easy to assemble and install, offer superior insulation and protection from potential electrical hazards, and are compatible with a wide range of wiring sizes. These benefits make them increasingly popular in a variety of industrial settings, making them an essential component in any electrical system.
