The DIN Rail

The DIN rail is a popular connector used widely in the industry for mounting components such as relays , meters, circuit breakers, etc. It is also known as the top-hat rail due to its shape which resembles an inverted hat. DIN is the acronym for Deutsches Institut für Normung e.V, the German national organization for standardization.

The standard DIN rail used is 35mm wide. However, there are types of the rail having lesser widths such as 15mm or 7.5 mm.

The European Standard EN 50022 and the IEC standard 60715 specify the DIN rail for mounting low voltage switchgear and controlgear.
