What is DIN Rail Mounting?
A DIN rail is a metal rail of a standard type widely used for mounting circuit breakers and industrial control equipment inside equipment racks. These products are typically made from cold rolled carbon steel sheet with a zinc-plated or chromated bright surface finish.
Basics of DIN Rail
This is a narrow channel of metal – made of bent sheet steel
or extruded aluminum – with edges designed for plastic components to “clip” on.

An obvious advantage of using DIN rail to secure electrical
components versus individually attaching those components to a subpanel with
their own sets of screws is convenience: much less labor is required to mount
and unmount a DIN rail-attached component than a component attached with its
own set of dedicated screws.
This convenience significantly eases the task of altering a
panel’s configuration. With so many different devices manufactured for DIN rail
mounting, it is easy to upgrade or alter a panel layout simply by unclipping
components, sliding them to new locations on the rail, or replacing them with
other types or styles of components.

An industry-standard structure for attaching terminal blocks
and small electrical components to flat metal panels is something called a DIN
rail.
The DIN rail itself mounts on to any flat surface by means of
screws inserted through the slots in its base. In most cases, the flat surface
in question is the metal sub-panel of an electrical enclosure to which all
electrical components in that enclosure are attached.
