Terminal Block Products

Terminal Blocks with Connectors

For the wiring of machines and system controls Siemens terminal blocks with Screw, Spring Loaded and Insulation Displacement Connections meet or exceed the requirements of CSA, IEC, NEMA, UL, VDE and other international Standards.  Meeting these requirements, combined with worldwide acceptability and availability, enables Siemens terminal blocks to be used domestically; and, incorporated into equipment which will be exported.


Virtually all terminal block bodies are insulated on both sides eliminating the need for barriers and end plates.  The materials used are ecologically harmless; e.g. cadmium-free, and without halogens or silicone.  The terminals are finger-touch safe and cannot be installed onto a mounting rail due to their symmetrical design. In response to these trends Siemens has expanded existing and added new terminal block lines.
