The heart of the Altech philosophy is the standardized DIN Rail and snap-on terminal block. The DIN Rail makes possible a compact, organized arrangement of terminal blocks and other DIN Rail mount components. This gives more than just the appearance of quality; it saves time and space, enhances design capabilities and provides a centralized connect-disconnect area where external and/or internal wiring can be connected quickly and efficiently. At the same time, the DIN concept allows designers to take advantage of constant advances in terminal block technology. The spring clamp series terminal blocks offer a time saving alternative to the popular screw clamp connection. The pre-stressed spring is opened using a tool (screw driver) so the conductor can be inserted into the insertion space through an opening in the spring leg. The conductor is pulled against the current bar under spring force when the tool is removed. A high contact force is achieved by the design of the spring clamp system. The design delivers a secure and reliable connection for any application.
