Terminal Blocks – What Are They?

Terminal blocks come in an infinite range of sizes, colours, and profiles but all types will contain metal parts shrouded or encased in plastic to prevent human contact with the electric current being carried!

Dinrail Terminal blocks 

Din-rails are typically made from cold-rolled steel with a zinc-plated or chromated bright surface finish. They are only used for mechanical support and should not be used to conduct electric current. They may, however, provide a ground or “earth” connection.

What is DIN Rail?

The term DIN-rail derives from the original specifications published by Deutsches Institut für Normung (DIN) in Germany, (from the 1920s), which have since been adopted as European (EN) and international (IEC) standards. In simple terms Din Rail allows multiple components to be mounted collectively onto a chassis plate rather than individually thus saving time!

In simple terms, “Terminal blocks” are used to neatly terminate wires and facilitate connections to an electrical supply. Terminal blocks are used in a multitude of applications in many sectors such as electronics, automotive, railway automation and process engineering industries ad infinitum!
