Terminal blocks consist of modular housings and insulators used to hold two or more wires together in electrical systems that require secure connections.
Terminal blocks, also known as screw terminals, terminal connectors, or connecting terminals, provide engineers with semi-permanent wire connections that provide organized and simplified inspection or repair capabilities in the field.
Although components are widely used in many applications, it is still important to have a basic understanding of common terminal block types and sizes before making a final selection.
Terminal blocks come in a variety of shapes and sizes to meet the needs of a variety of complex electrical system connections. Pay attention to key electrical and mechanical specifications and different module types to find the right terminal block for the job.
