How Din Rail works

DIN rail is a metal rail used to mount various electrical components, such as circuit breakers, terminal blocks, and relays, in a standardized way. The name DIN comes from the German Institute for Standardization (Deutsches Institut für Normung), which is responsible for creating and maintaining the DIN standards.

DIN rails typically have a standardized width of 35mm, and they come in different lengths. The most common type of DIN rail is made of steel or aluminum and has a symmetrical, hat-shaped cross-section, with a top hat and a bottom lip that can snap onto a mounting bracket.

To install electrical components on a DIN rail, the component is equipped with a mounting bracket that snaps onto the DIN rail. The mounting bracket is typically made of plastic or metal and has two or more clips that grip onto the DIN rail. Once the component is clipped onto the DIN rail, it is securely mounted and can be wired to other components.

One of the benefits of using DIN rails is that they provide a flexible and standardized way to mount electrical components, allowing for easy installation, removal, and replacement. DIN rails also provide a space-saving solution, as components can be mounted close together without interfering with each other.

In summary, DIN rail is a standardized metal rail used to mount electrical components, providing a flexible and space-saving solution for electrical installations.
