RS PRO Feed Through Terminal Block, 120mm², 1-Level, Bolt Termination

Feed through terminal blocks, also known as pass-through terminal blocks or through terminal blocks, are electrical connectors used to create secure and reliable connections for electrical wires. The design of feed through terminal blocks allows wires to be inserted from both sides, passing through the terminal block, and contacting the internal conducting elements.

Feedthrough terminal blocks provide a convenient solution for maintenance and modifications. As the wires pass through the block, individual wires can be disconnected or added without affecting the rest of the circuit. This flexibility makes it easier to make changes or repairs in complex electrical systems.

Feedthrough terminal blocks are available in various sizes, configurations, and materials to accommodate different wire gauges, current ratings, and environmental conditions. They can be found in both screw-type and spring-type designs, catering to different installation preferences.
