In general, a terminal block is an electrical connection point that holds and organizes wire ends so circuits can be joined, tested or isolated without splicing individual conductors. In heavy equipment it is typically found in control and wiring assemblies, where it helps keep harness connections organized and serviceable.
Please confirm that part number 0111806 is the exact item you need before ordering. Because the catalog association is only an occurrence within a larger controls arrangement, check the machine model, serial and configuration conditions recorded in the catalog for that entry, and contact the supplier if your application may differ.
