The terminal block consists of a modular shell and an insulator, which can fix two or more wires together. Terminals are also called terminal connectors, connecting terminals or screw terminals.

Terminal blocks are used in various applications that require safe connection to electrical systems. They are very suitable for designs that require safe, well-organized and semi-permanent wire connections that can be easily replaced for on-site inspection or maintenance.

When designing a system that will use terminal blocks, you may understand your overall system voltage and current requirements. Although these are very important, there are other factors that you need to consider in your design.
