What is rail din?

Rail din, also known as DIN rail, is a type of metal rail used to mount various electrical components, such as circuit breakers, contactors, relays, power supplies, and terminals. It originated in Germany and stands for Deutsche Industrie Norm (German industrial standard).

Rail din provides a standardized method of mounting electrical components within an enclosure or on a panel. Its dimensions are based on international standards set by the International Electro-technical Commission (IEC) and range from the smallest size of 15mm to the largest size of 107mm.

Rail din allows for quick and easy installation, reducing the time and effort required to install and replace components. It also offers easy access to components, simplifies wiring, and improves maintenance and repair.

Rail din can be made from different materials such as steel, stainless steel, aluminum, or plastic. It also comes in different colors to match specific industry standards. Its use is common in industrial control systems, building automation, process control, and power distribution applications.
