What are DIN rails?

DIN rails are lengthy metal strips that make up the primary component of an internationally recognized standard mounting system used in equipment cabinet racks. They are intended to provide a secure attachment point for a variety of electrical and industrial control products, including circuit breakers, terminal blocks, power supplies, actuators, solenoids, and more, within a standard cabinet or frame used to enclose the equipment.

DIN rails serve only as mechanical support structures for components and are not intended to function as connectors or conductors within an electrical system. In other words, they are not equivalent to busbars, although in some situations they may be used as grounding busbars.

Advantages of a DIN rail system

Efficient and Time-saving: They offer a time-saving and efficient solution, as components can be easily snapped or slid into place on the rail, rather than having to panel mount each individual component separately.

Space-saving: They enable space-saving configurations of components, making it possible to bring internal and external wiring circuits together in a convenient location, allowing for tight arrangements of the components. This makes them an ideal solution for limited space applications where space is at a premium.

Cost-effective: DIN rails are cost-effective, both in terms of DIN rail pricing itself and the potential for high-density adjacent mounting, which can significantly reduce the overall amount of wiring and cabinet space needed.

Nowadays most controls components are mounted on standard 35mm Din Rail which is in turn mounted on Control Panel Backplates. When using DIN Rail as a Ground Terminal Block, particular attention must be paid to the short circuit properties of the rail. With the use of a DIN rail ground (protective conductor) terminal block, the DIN Rail itself can be used as the Grounding Terminal Block. The following is an example of how the system works to create a path to ground.
