A DIN rail enclosure or a DIN rail box is an enclosure to which one or more DIN rails may be mounted. A DIN rail is a flat metal
bar of standardized dimensions that provides a convenient means of mounting components to a wall or inside an enclosure
Installers simply snap or slide components into place on the rail.
This is a popular format in control applications because the components tend to be modular and can be easily changed:
power supplies, solenoids, actuators, circuit breakers, and terminal blocks.
